iOS 15.5: iPhone XS discontinues e-mail receiving after some time of correct functionality
After a reboot all works fine and the iPhone is receiving e-mail in the defined period of time (30 minutes). After some time of correct functionality, the iPhone discontinues e-mail receiving. For receiving of e-mails I've to open explicitly the e-mail app. I didn't change anything in the e-mail preferences. What's wrong? Very annoying.
iPhone XS, iOS 15
