Great. Google have added a level of bureaucracy to their OAuth, requiring apps be verified before people can grant access to their accounts.
Since I missed the initial notice this was happening, and the verification process can take *weeks*, the #mailpile credentials may be disabled. Nobody will be able to download their mail for who knows how long.
Nothing anti-competitive to see here, this is fine. Just use the official Google apps, you'll have fewer problems.
In the name of security... 😞
