the ads are too well tailored now
Assuming this is the youtube app, to avoid ads I recommend either LibreTube and NewPipe (I have used these), or patching the yt app with revanced (I have heard great things about it but never got it to work)
No need to patch it yourself. Just follow instructions here.
if you're struggling to use the official manager (which fair enough, it can be quite confusing) there are really good third party tools like https://github.com/decipher3114/Revancify or https://github.com/reisxd/revanced-builder
