Ok, just bought Z11 pro and it's pretty straightforward in the iptv department. I'm enjoying my provider right now with a live match, no freezes, AFR is working pretty dope and the only time i've got connection lost error 401 was when i did a huge update on my fire stick that affected the formuler, other than that everything seems good in the iptv deparment
Now there is some problems in android permissions and i know why because i have nvidia shield and it happened there too, somehow they fixed it with a popup message that allowed the file explorer app (x-plore, fx, es, etc) to access those files ( inside internal storage -> android -> data) and we just needed to say yes, but it transported us to another app, a file explorer app that came with the rom and that's what i think is missing in the formuler. Because the popup appears on file explorer + but there is no file explorer system app to do it, so there is no way to access those files and while it's not a major issue for many, for me in kodi is very important to access those files.
Given i know this is an android 11 issue i'm going to try to find workarounds but i wanted just to let you know about my experience.
I also have a minor issue in AFR of both Kodi and Plex, meaning it works like charm, both refresh rates work ( 23,976HZ and integer values like 24HZ which is a big relief) but it always change resolution from 1080p to 4k. I would love to be able to keep it at 1080p for some movies. Still a minor issue because there is a workaround in Kodi at least by disabling AFR and put it manually before every movie but it's a bit boring to do that every time and sometimes we don't know the stuff we have in 24fps and 23,976fps, so there's that.
Keep up the good work
