Several time a day while I am using Mail I get the triangle and I am unable to send or receive my iCloud email. I have checked my Mail settings and they are correct. I also go to iCloud via the web and it is working properly so I can only conclude there is a bug between Mail and iCloud. The issue will eventually go away but it has occurred about 5 times each day. Any thoughts?
