Hi - I have been experiencing this recently as well. It has happened a few times over the last year, but the frequency with which it is occurring is increasing (22nd, and 25th this month).
Although a simple fix to disable, restart, enable, restart - it's a right royal pain to have to keep doing this 'fix'
