Notification Service extension stops working after application update until we reboot the device

We have noticed that the notification service extension stops working after app update for some users and it only starts working again after rebooting the device. Does anybody else have similar problem and what was the solution?

This is a known issue currently being investigated. The only available solution at this time is to reboot the device to clear the problem state.
