On our pixel pro 6 works with only one Gmail account now! Why! Pixel 5 phone was able to deal with two! Thank you! I had been trying to add the second account for 3 days (new phone). Each time I successfully (many failures) got the second one added, I was logged\removed from or out of the original, the 'master' one. Re entering the original - deleted the second. Half hour ago, I tried again. Success! Something got settled in the internal workings? Anyway thank you.
