So to beat a dead horse and deepen the mystery, I have been trying about once a week to sign in to AG using my normal, everyday browser, Brave, and every time it rejects my username and/or the password stored in my Apple chain, despite the fact I was finally able to get on using Safari and the very same credentials
I tried it again this weekend for the umpteenth time, and voila, I was able to log on
I STILL can't use the stored password to CHANGE my password but at least I don't have to keep 2 browsers running at the same time
I saw Bunky was able to get back in somehow
This whole thing is just wacky
