The Thunderbird for Android app on my Moto G 5G has a problem with Gmail. For some unknown reason I am receiving several authentification failed notifications per day sometimes 3 or 4 in a row. I uninstalled the app for now in hopes that maybe someone has an answer to this problem. I have Hotmail, and Yahoo mail also on the app without any problems at all, I followed all of the instructions given when I downloaded the app.
