Re: [PLUG] Quantum fiber WhatsApp latency issue
An great thorough reply! If I cared enough to undertake all this, I'd do exactly what you suggested. Fortunately I have more curiosity than concern & PLUG has adequately appeased my curiosity.

Re: [PLUG] Quantum fiber WhatsApp latency issue
I would agree with you except that when I switch over to my other WiFi (I have 2 different ISPs here) WhatsApp has no latency. Also no other app (signal gv etc) have latency on either ISP. It's only WhatsApp when using quantum fiber. Also it's not consistent; sometimes it's immediate for half day while sometimes it's 2-10 min latency for half day. But you are correct, no latency ever on either ISP for WhatsApp calls. It is only for messages. Overall, your push notifications explanation makes sense. & I can live with this latency too; idc, nothing anyone sends or shares is worth the immediacy humans think they merit. But what conspiracy theories? I am ok being Meta's product in exchange for this free service. All these ppl running around complaining about that but still using all this social media crap are humorous hypocrisy at best.

Re: [PLUG] Quantum fiber WhatsApp latency issue
This is because of a fundamental misunderstanding of how cell phone apps like whazzupapp work. I would bet money you are NOT seeing this "latency" when you make a phone call from your whatsapp to another whatsapp on some other cell phone. It's only when you are sending instant messages. Let me explain what's likely going on here. The whatsapp app likely uses push notification. What that means is when your phone is on your cellular data network the app registers into the cell tower. Then goes to sleep. When a text comes to you, the tower sends out a push notification that wakes up the whatsapp app on your phone and you get the text. This allows minimal battery usage on your phone. Here's a dumbed-down explanation of push https://www.airship.com/resources/explainer/push-notifications-explained/ Anyway, the whatsapp almost certainly has push turned OFF when the phone is on a wifi data network because they have to pay the mobile carriers for push access. In that case the app is polling the server over the internet. Likely once every 10 minutes. Otherwise their server would melt down if it polled every second. There have been complaints on "latency" on this app for over a decade. Here's a typical one: https://xdaforums.com/t/whatsapp-messages-delayed-only-on-my-home-wifi.1941623/ There ain't nuthin wrong with anything here. The app is working as it's designed to work. If you live in the US of A, a free country with privacy rights then set aside your conspiracy theories and toss whatsapp in the garbage. If you live in China, my condolences you are stuck with this behavior. But at least the men in black won't be breaking down your door in the middle of the night.

It has latency issues with WhatsApp. Any idea why & how to resolve this? I've no other issues with them. Using the WiFi. All other sites apps etc have no noticeable latency. WhatsApp takes minutes to send a message & receives messages minutes after someone sends. However if I turn of WiFi & switch to cellular data (TMO) it immediately sends & receives the backlogged messages. The latency can be up to 10 min sometimes. Thoughts?
