Hello,
The answer is no. They should not see the “unverified app” message if the application is whitelisted. We can confirm this by reviewing this Gsuite updates documentation <https://gsuiteupdates.googleblog.com/2019/06/third-party-apps-gmail-data.html> which I understand is not the clearest but it does states that after july 8, New users will not be able to install unverified apps unless you “trust them” which would be whitelisting. Hence, after whitelisting, the “unverified app” message should not be displayed. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
