Q: mail loses iCloud password when I close app

Deleting the account lead down the path to the solutions.

There appears to be a couple of issues. If your credit card on file expires it

appears the system renders your account not usable until you either delete the card

or update the record. I say this as I deleted my email account and reinstalled to no

avail, then I looked at the account itself and saw that my CC info had an alert,

I changed/updated it and then deleted and reinstalled and all works well.

Thanks
