Revanced stopped working for me a few weeks ago now. It will just play like the first minute of a video, and then get stuck on an infinite loading. Searching the web for that issue, I got the idea that my account was flagged somehow. I’ve tried uninstalling ans reinstalling and it doesn’t help. Tried it again after a few weeks to see if it had started working again, no luck.
The thing is that first you pay in order to avoid ads, but ads will start creeping in on the paid version in no time. Some day you’ll find yourself paying and still seeing as many ads as they decide to push. The same has been done in other platforms. Cable TV didn’t have ads when I was a kid, “because it was paid”.
