Only gripe is your stuck to the web version of youtube (especially on ios).
If you want sponsorblock in the native youtube app you have to side load a mod which means either dealing with apple’s 7 day limit refresh or paying for a apple dev acount/ signing service subscription.
Android there is revanced (no sideloading subscriptions needed).
On a final note I am considering trying grayjay.app
It bundles odessy, nebula, youtube and a few other platforms in one app (it also includes sponsorblock and return dislikes for youtube).
