Anyone else having his issue? Started with 10.12.4b1
I have two GMail accounts set up in Apple Mail. I have these same two accounts set up in Apple Mail in TWO different Sierra accounts and this happens on both. The machine is up 24/7. It seems like Apple Mail forgets the GMail passwords every 24 hours.
It's not the passwords as my iOS devices work fine all day, day after day, accessing these same accounts.
Is this a security feature maybe? It looks like the accounts are in the keychain.
