HELP WITH AMAZON FIRE PVR CONNECTION LOST

Hi, I am a complete Newbie to this. I’ve searched the threads but haven’t found an answer to my precise problem. If it has been posted already, I do apologize. I just got a new Amazon Fire Box and installed Kodi and the Fusion Add-on. No problem. I tried to get live TV by installing a PVR client on Kodi via Settings/AddOns/PVR- I enabled NextPVR and enabled live TV in settings. No TV option popped up on menu screen. Then, I exited out and logged back in. “Connection Lost” error appeared. I tried this with MULTIPLE PVRs and NONE worked except–IPTV SIMPLE CLIENT, but that one doesn’t work for Live TV anymore (I guess the “test” is over). Can someone please tell me what I’m doing wrong? I am pulling out my hair trying to get this to work. Thank you!
