I was watching TV and all of a sudden it stopped working. Getting authentication failed. Anyone else?

I just upgraded to Kodi 16.1 and I'm getting the authentication failed message. Settings have not changed and are still working on my Kodi 15.2 machines. Did all kinds of resets, to no avail. How do I get Stalker Client to work on Kodi 16.1? Thanks

Don't know if it's Dish or DirecTV, or both, but all the American channels I've tried aren't loading. Non-American channels all have extreme buffering problems for me, so I can't really watch them.

The guide was OK for a few days, and now it's off an hour, again! Can they fix this for good????

The major networks NBC, CBS and FOX used to be the first channels listed in the EPG, but they haven't been available for a few weeks.

It seems I've tried everything to fix my 1 hour EPG setting, tried both ninja NFPSE and NFPSED, cleared data each time, rebooted, etc. The EPG is always an hour off. For example, if it's 8:00, I have to look at 7:00 for shows playing right now. I'm using Stalker Client with the ninja EPG.

Where did the PPV channels go? They've been gone for a long time. I was hoping they would come back, but they didn't and I'm really missing them.

I have an android TV box with consistent 33 mbps internet speed going to it (Ethernet connection). I've noticed that most of the buffering issues I have are on UK channels. It buffers for a second or so every 5 to 10 seconds. Pretty much unwatchable. Is there a way to fix buffering issues on...
