Lately I've been having trouble with my iCloud email app on my iPhone 6+ not connecting at all whether I'm on wifi or not. I thought it's my network settings but my other email accounts are connecting ok, gmail, yahoo and hotmail. The only time it works is when i close any running background apps or if do a restart or shut down my iPhone. It wasn't like that before. I think it started when I bought an Apple Watch and paired it with my iPhone but I could be wrong. It only started doing this about a week only. Anybody else having this problem?
