I have a problem with a new blackberry key2 and app blackberry hub+ inbox.
If I receive a new email which will be moved to a subfolder via MS exchange rule I only got a vibration and no sound notification.
Selected sound is the default one or a custom both don't work even with factory default settings and just an exchange account with notification enabled it won't work.
DND is disabled and sound is on.
Any advice where the problem can be?
