Did you migrate/restore anything (i.e. config) from the WP1 install? .. I'm using a WP2 with the stock remote as my current 'daily driver' and there's no repeat issues in the default image.
I didn't migrate anything. Started the system from scratch, and just got my watched data from trakt after installing that add-on.
And now, without me having done ANYTHING, not even rebooting the device (which I tried before and it had failed) - it works again!
Weird.
