Adblock, UBlock Origin, or if you're set-top box (Android, Apple TV, etc) has the ability to download apks, get SmartTubeNext. Skips commercials, and can even skip the stupid adverts that the video has that is made by the creator. "Oh that reminds me, when I have an itchy ass I use Gunderson's butthole cream" or whatever, it automatically skips that shit.
It can even sometimes skip off topic shit lol. Sometimes creators ramble on about something other than the topic of the vid and it skips it. It's glorious.
Youtube vanced or whatever it was called. Was shut down recently.
What? I just googled and yeah, it looks like they are shutting it down. Good thing I have the app installed and it still works for now. If it stops working then another will take its place, or I'll use some other means to search for videos on my phone. That's all I use it for on my phone anyway. I use SmartTubeNext on my NVidia shield and it works awesome.
