I subscribed for one month of vaderstream, and configured both the APK and Perfect Player on my Nvidia shield. Every channel buffers non-stop. I have 100/20 mbps internet and I tried watching with and without my VPN and tested various tunnel endpoints. I have another app that I use specifically for for Japanese IPTV that works without issue, so the problem is unlikely to be on my end.
I contacted support via their telegram group. I followed the rules to create a support request. As I was explaining my problem the moderator started deleting my posts. The last post I made was something to the affect of "are you really deleting my posts?" I was then banned from the channel, which leaves me as a paying customer with no method of getting support.
I suppose this is my fault for not starting with their free trial, but jeez... at this point I can only hope that my subscription does not renew at the end of the month since their website has no information on cancelling.
I tried Vader’s a couple times, was always buffering. I’ve no idea why people bother with it.
