Email doesn't delete on iPad after deletion by iMac or iPhone
My iPad 3rd Gen 64Gb running iOS8.1.1 steadfast;y refuses to delete emails that have already been deleted from another device or iCloud or update them as moved or read, and I have to go in and remove/move them manually. iPhone 6+ and 2014 27" iMac both work with each other and iCloud perfectly, deleting and marking as read or moving files about in folders. The other devices respond to what has happened on the iPad.
With iPhone 6+ I am finding the iPad next to redundant and this issue is fast speeding a disposal decision!
If anyone can advise I would be most grateful.
iPad 2, iOS 8.1, May 2012
