App-specific passwords not working
For two months, I have been trying to get App-specific passwords to work. I managed to authorize Spark on my iPhone, but no desktop apps are being authorized. This is particularly infuriating because I'm trying to find a new mail app for my MacBook Pro, since back in September of 2019, when Mail stopped being able to send mail through my iCloud account.
So far, I've tried creating, copy-pasting the app-specific password into he app.
Failed.
Deleted the password. Generate a new one.
Failed.
Kept a copy of the password, tried a day later.
Failed.
Tried a week later.
Failed.
Generated a fresh password. Waited an hour.
Failed.
There isn't much documentation and everything seems like it should be straight forward, but I'm about to give up and go back to Gmail.
