Gmail not accetping Thunderbird as app

more options

Hello I have using Thunderbird to manage 5 email accounts of which one is from gmail. yesterday, I created a second gmail account, that I am trying to add to Thunderbird. I have the correct gmail config setup for the new account using OAUTH2. I have turned on the Less secure App pref in Gmail. But when thunderbird offers to login to this account, I eventually get to the accept Thunderbird as app gmail page and accept, the connection fails. I do not have this issue with the first gmail account. If I understand correctly, OAUTH2 used a token system to avoid passwords. Is it possible that trying to have 2 OAUTH2 gmail accounts is causing a conflict? Any ideas are most welcome

Account 7 is the account I cannot make work.

You'll need to upgrade to v68.2.1 at least. That fixes a Google OAuth issue. In the meantime, there is a workaround.

Edit/Preferences/Advanced/General/Config. editor, double-click general.useragent.compatMode.firefox to true.

Note, the current release version is Thunderbird 68.2.2.
