I've been using Channels almost exclusively since I believe around February. I use the Android Client on my Nvidia Shield. At some point I had the spinning circle buffering issue but I hadn't seen that happen for months.
With today being the start of football season for my team, I'm watching the NBC Sunday Night Football broadcast on NBC. The spinning circle buffering issue came back with a vengeance. It was happening sporadically, but often... sometimes multiple times a minute. I finally couldn't take it anymore and switched over to Kodi. Guess what? It didn't happen one single time.
There is definitely an issue with the Channels Android client. Can the devs acknowledge once and for all that there is an issue and start looking into it? I don't want anybody to tell me it's my network, because if it were, Kodi would experience the problem and it absolutely did not.
Are sporting events like SNF implementing a higher bitrate Channels can't keep up with or something like that?
I guess from this point forward, I'm going to watch my sports on Kodi, but I really hate using multiple apps for my TV watching.
Since I'm recording this game, I will check the recording once it complete and see if the problem is also there.
