Certain streamer or all ? Live?

Not surprised if only particular streamer since Twitch has so many servers. Still my first month with Unifi. Just now watching YouTube LPL playoff, it buffer for 15minutes which forced me to use my data. After that it returned to normal.

I havent encounter any problem with twitch yet, but when I was using Maxis fibre, I would occasionally get buffering when watching LCK after 8pm. I also tried and managed to get it fixed by switching from 1080p50 to 720p which wasn't ideal for my 65" TV.
