TubeRepair by bag.xml has just been released & is now in beta. (as of now, it’s only been around for abt a day.)
Original Reddit post by bag.xml
This completely revives the YT app for iOS 5.1.1 and now you can
use YT with no bugs, just like it was back in the 2010’s.
TUTORIAL:
UNINSTALL “TUBEFIXER” AND “CLASSIC YT APP” FROM IPG BEFORE STARTING.
Classic YouTube App (restore the app, API key, YT fixer)- most vintage, also the slowest method
m.youtube.com (GSignIn tweak from IPG)- allows you to sign in, quite fast
m.youtube.com/subscriptions - same as 3 but even faster, though this leads you to a 404 error page, it gives you a YouTube search bar, so no time is wasted loading recommended page.
