iOS 17.1.1 email issues
Since installing iOS 17.1.1, all email accounts (including iCloud, Gmail, Yahoo) only update after restarting the iPhone. Otherwise, they generate a “Cannot Get Mail. The connection to the server failed” error. I’ve already reentered passwords; the error only returns. This is clearly a 17.1.1 issue, as it didn’t exist for me as a problem before then.
