Issues are listed below:

*I use a m3u sub as a backup with apps like IPTV extreme, PP etc...it worked awhile back when I first used it now when trying to watch any channels on it, it loads up all groups and channels fine, however when selecting a channel it says error trying to play video. The service works fine on my Galaxy S8 so it is not server side issue. Some setting within the T1/T2 I think. I use a M3u style as a back up so I can use it anywhere on any of my devices, I do use a primary service with DOL2, however sometimes the primary server down or laggy.

*another issue on both T1/T2, when trying to use apps like NHL and Amazon Prime Video, the apps request location to be turned on the device. So I proceed to settings, find the location settings, try to access them and the device exits out of the settings menu. Won't let them be turned on. Any way to unlock the location settings on these devices?

EDIT So I spoke with the seller and it turns out that they announced via their Facebook page that VPN will no longer be allowed. I rarely check their page so it was unknown to me at the time. Unsure why it can't be used, but that's why the service worked previously and not now. I forgot to mention that I typically run VPN always on my stb's by default. So m3u's are back up and running. Still having issues with the location settings though. I know I get most NHL games via IPTV, however with my cellphone plan I get NHL Gamecenter "FREE" so it would be nice to have that for use as well. Also I have amazon prime so using their video service on the stb would be nice also.
