suddenly on Thursday afternoon (4/21/22), Thunderbird could no longer retrieve mail on one of my gmail accounts. I could still send, however. when I clicked 'get messages' I got a popup: One account. All of Google. Sign in with your Google Account but it won't let me sign in-- just keeps asking for my email or phone number but enter it and it asks the same question again. at the same time, I could get mail on my other 2 gmails but couldn't send from them. a few times when I tried to send mail, I got a message about my settings. I hadn't changed any settings, they are the same for all of my 3 gmail addresses. the other two emails that couldn't send, suddenly resolved on its own today and I can send emails on them again. I have full function with gmail (on browser, phone, laptop) just not with Thunderbird on my desktop. Was there an update on Thursday that did this to me? Have you been hearing from others with this problem? Did Google do something? thanks
