Starting a few days ago, Thunderbird began marking every incoming Email from my Yahoo account as Junk mail, with a red flame icon and the Thunderbird thinks this message is Junk mail banner. It even flagged the Account Confirmation Email from Firefox Accounts when I set up an account to post this message. The real problem is that it won't accept marking the Email as Not Junk. The banner disappears for about a second, then pops right back. This interferes with the Options banner I normally see, and prevents me from downloading remote content. I assumed the problem had to be on Yahoo's end because it's not occurring with non-Yahoo Email accounts, and because of the revert-to-junk behavior. But Yahoo's browser-based Email client shows no indication that any messages are being flagged as spam or junk. I've tried restarting Thunderbird, disabling adaptive junk mail controls, and resetting training data. No change. Thunderbird version is 105.0b1, build ID 20220822183911. Yahoo is set up as IMAP. Any thoughts? Thanks!
