Hi, I am aware of the changes Google made circa the 30th May 2022 which affect my ability to get emails from gmail via Thunderbird. I have several gmail accounts each account being on a seperate PC. I successfully changed the sign in proceedure on all but two computers by changing the Authentication Method in Server Settings from Normal Password to AOuth2 following guidlines I found on the internet, signed into the relevant Google Account and gave permission for Thunderbird to access the relevant gmail account. This is the problem I am experiencing on the 2 computers mentioned above:= I followed the same proceedure, changed the Authentication Method to AOth2 and Thunderbird presents me (on opening) the necessary Google Window for me to sign in to my Google Account. The correct email address is already shown in the Email/Phone Box but when I select "next" to enter my password, the Google Window re-appears but with the email address blank ie. it does not take me to the passweor page. If I fill in the email address and again select Next, the same thing happens ad infinitum. I know that it must be Thunderbird that is preventing the login to my Google Account because I have no problem logging into my Google Account if I complete the Google sign in page from my browser. It is exactly the same problem on the 2 computers each with its own different gmail email account. Any ideas? Thank you
