On my ipad air 2, my icloud.com emails won't download to folders with rules unless I manually open the folders
I have a xxxx@icloud.com account that I use on my iphone, imac, and ipad air 2. I have created several folders and message rules for those folders. The messages download automatically and show in those folders on my iphone, and imac.
However, on my ipad air 2. in order to retrieve messages sent to the folders by rules, I have to open the folders manually and then the messages download.
Example would I receive 10 new messages that route to my my "work" folder. those 10 messages show just fine on imac, and iphone in the work folder as new messages. On the Ipad it shows nothing until I open the "work" folder and then the messages proceed to download.
Any help would be appreciated on resolving this.
iPad Air, iOS 8.1.2
