It has SponsorBlock it's just disabled by default, you have to go enable it.
My Revanced app quit working right and I'm kinda nervous about updating it again because I can't remember where I got it so it's just a little too much risk now. Thus I've been using Grayjay more.
I like subscription groups but I don't like that it only imports subs from YT instead of a sync. So if I unsub from a channel from my computer, it doesn't unsub in Grayjay even if I import again, I have to go do it manually.
They also need to work on the other site plugins more. YT seems to be the only one live streams work with. They will show up for Odysee but they don't work and I never even see live streams for Rumble. The Kick plugin seems to have completely broken and it's been broken for a while.
There's also one channel I unsubbed from both from my computer and in Grayjay, but I'm still seeing new videos from it show up in my subs feed in Grayjay so something is broken there.
