I assume you had it on both (the default), not short, before the switch?
I will give that a try, shouldn’t be any downside I don’t think.
I’m wanting to try stuff that has worked for other people, not
random stuff.

I changed one to long and the key exchange drops seem to have vanished.

I have it set to both. I thought the issue was if you set it to
short only.

Been seeing alot of this with apple devices that have issues staying
connected or connecting in general and changing the preamble setting
to long seems to fix
most issues

The complaining customer called today and said the issue is 99%
fixed after I changed the group key exchange from 5m to 60m,
which unfortunately is as long as RouterOS lets you set it. I
believe this is the interval for rotating the group ciphers, not
the timeout for the exchange. Not sure why the Apple devices
seem to be not doing the handshake for the new keys, resulting
in them getting deauthed and disconnected.
The only other thing I am considering is changing channel width
from 20/40 to 20 MHz. There’s a list of tips from Apple that
says to do that in 2.4 GHz, but they seem to imply it’s for
compatibility with other devices, not specifically iOS devices.
The other thing Apple recommends is enabling WMM, I’m not sure
if that’s a good idea, especially since Mikrotik doesn’t support
WMM sleep mode, AFAIK. I’m not sure why just the QoS part of
WMM would prevent a client from getting disconnected.

I’ve seen plenty of iOS devices throw fits whenever the wireless
access point is set to auto frequency selection. Some
iPads/iPhones/etc. get left behind when the channel switches.

Let’s not get sidetracked with a discussion of downgrading, I
don’t think that’s relevant here. I do understand what you’re
saying about the changelog – Mikrotik may have changed/fixed
something from 6.19 to 6.29 silently without noting it in the
changelog.
I was kind of hoping someone knew a trick to get the Netflix app
to just keep playing rather than popping up an error message.
Or had seen this problem before and knew how to fix it.
The group key exchange timeout may be a red herring. I’m not
sure if Mikrotik is doing a good thing by kicking the client off
when the group key exchange fails after a key rotation. I guess
it prevents a situation where the client can’t talk to other
clients on the same LAN because multicast/broadcast traffic
isn’t getting through. But maybe it would be less intrusive to
just wait for the next key rotation to restore that
functionality rather than forcing a disconnect. Also I’m not
sure why they won’t let you set the key rotation interval longer
than 1 hour or turn off rotation entirely, probably for security
reasons.

The don't downgrade applies to ROS version and firmware. There
may not be an issue with a given product and two versions, but
it's a good habit to get into.
Mikrotik's changelog is like cheating on your spouse. Everyone
sees you behaving differently now, but there's no official
paperwork showing it.

This particular router has Routerboard FW 3.18 so I think it was
upgraded to 6.19 not downgraded. Also, I don’t see any wireless
related changes in the changelog from 6.19 to 6.29.
I’m thinking of changing the group key update interval from 5m
to 1h which I think is the max. I’m not sure if the group key
exchange timeouts are due to the client being in sleep mode, or
a problem I should be worrying about. The fact that the
Mikrotik sends deauth to disconnect the client which then
immediately connects doesn’t seem like a good think. Without
the deauth and disconnect, I would not expect unicast traffic to
be affected. I’m thinking the iPad knows the WiFi disconnected
and tells the app which then pops up the annoying error which
requires the user to tap OK and then Play.
If I change the timeout to 1h and the frequency of the problem
stays the same, I think that will eliminate this as the possible
cause.
Reading the logs can be confusing, it’s amazing how many iPhones
and iPads one family can have. Hard to sort out the problems
from normal events.

I don't believe you're ever supposed to downgrade a device's
shipped software, due to unknown chipset\driver changes.

Actually no, I have everything on 6.19 because it was stable for
me and I
don't like facing the choice of either upgrading everything in
the field
every month or having every router on a different version. I've
even been
downgrading the latest shipment of 951G's that came in with 6.23.
Usually switching to Mikrotik from store bought routers solves a
lot of
iPad/iPhone problems for us.
He said this is the latest iPad, would that be the iPad Air 2?
I remember
the iPad Air being new 2 Christmases ago.

Apple devices are picky on their wifi stuff when it comes to
mikrotik. I
assume you have upgraded to the latest version of RouterOS. This
is one of
the few times running the latest helps. I was running 6.21 on
one of my APs
in the house and anytime I roamed to it things became very
slow. OS upgrade
helped.
Is this an iPad, Ipad2, iPad Air?
