You must be having a Kodi moment! LOL 
Miki, I think we have the same iptv service and nothing shows up on the Olympic channels. really disappointed. I do have a hit or miss in recordings for TM. I’m trying sparkle to see if it’s different. I wonder why you show programming on your Olympic channels but mine are blank
My IPTV gave me Olympic channels in Astros, Europe sport at UK and another country. However they didn’t give me any EPG so it’s very hard to chase something down you want to watch. NBC, channel E! Have some Olympics on it.
Both my subs show full olympic events. A complete EPG. Did you update your EPG. I have mine set to update on app start as well as on playlist change and update every 4 hrs. No idea why you would have any issue on the Shield Pro with recordings. The last update fixed the 'droid 11 limits as well as giving full access to the System Picker which will also give you the permissions options. Using X-plore you can also check the permissions and allow them for the Data and obb folders.
Buy a new or used Amazon kindle. It will work for you to get the app or any other android device.
