Whenever I configure in Thunderbird, OAuh2.0 with google, I get the pop up with prefilled account name as soon as starting up or synchronizing, but as soon as I click anything or type anything in the google box, the prefilled name disappears. Refilling it does not work either, the page / box, just reloads and the (pre)filled name is gone. Logging in at the same time in a web-browser and staying logged in, does not work either. Switching on or off my VPN does not work either, (this has caused major problems in the past, to access my accounts anyway). Only using "normal password" and the setting "allow unsecured apps" in Google, works as work around However Google is ending the support for this option in a month or so. I have seen multiple (old) posts about this, but not found the one where my issue of a reloading page without prefilled name occurs.. Please advice, yeah stop using google hehe, no but seriously... wtf. Win10 Thunderbird 91.8.1 64 bits
