In iOS 9.2 there are many interesting possibilities, also Apple has fixed several critical errors. But without new troubles, unfortunately, there were some users began to notice the incorrect operation of the standard Mail app with Gmail accounts and other services except iCloud.
As it turned out, the problem is that now the email is not from iCloud are delivered without push notifications. They do not support this feature, so for the other boxes you can select only “Sample” — uploading new messages every 15 minutes, 30 minutes, hourly or manually.
Turns out quickly to get a new e-mail will not work. Not very convenient if you are waiting for an important letter that requires an answer immediately upon receipt. Especially important for business accounts.
The existence of the problem confirmed to our source close to Apple. It is unclear whether the company something to do with it, but before the release of the new version of iOS at its decision not to hope.
