I have two Google Mail accounts configured to send and receive email on evolution. One is personal and one is official. The official one is a GSuite account. Every day, and sometimes many times in a day evolution reports and inability to receive or send email from these accounts. The error reported is either an authentication error or a timeout error. A message popup shows an option to "reconnect". Clicking that opens up a dialog box for Google (OAuth) authentication and google asks me to allow GNOME Evolution to do this or that. I have to click allow and after that it may work or I may have to restart my computer to reconnect on evolution.
After I complete the authentication process I receive a message from Google that I signed in from an unknown device, whereas it is the same notebook computer from which I have been connecting for several months.
I am reporting this as an issue with evolution because Google for some reason treats it as a less secure app. In order to access my email from evolution I have to turn ON the "allow less secure apps" setting at Google.

Periodically, after working for a few hours, evolution may suddenly throw up a "timeout was reached" when sending a message. Then connections to imap folders also stops. I have to reboot in order to get things going again. After a reboot, the same message in the outbox, which was showing the timeout error gets sent
