Thank you @chuckster007 , appreciated.
HBO channels are often stuck in a 2-3min repeating loop. At least the Canadian news channels (under USA) work but Comedy network and the good documentary channels remain deleted from this update.
Tried a number of other apps they offer but none of them are suitable. Been looking at getting "The Boss" android box but without a channel list for their live TV app it could be just a waste of money.
