Yes... same problem here. I accessed my AOL mail account via Safari, my iPhone 12 Pro and my MacBook Pro.
About 10 days ago, I was suddenly unable to access my AOL mail account via Safari. And today, while I was able to get email on my iPhone in the mornings, sometime after lunch, my iPhone began spitting out errors for an invalid password when using my iPhone.
Now I'm down to my MacBook email client only.
Tried calling AOL support and actually got through. But when I mentioned "APP-Specific password" to support, she had no idea what that was. I'm sure you can figure out how that call went...
