Quick shout-out to Grayjay: An app to watch videos on any platform - reducing the power of individual services. The Software is open-source and can be found here: https://gitlab.futo.org/videostreaming/grayjay
I will test this out for myself and hope someone here finds this useful.
Yattee, it’s an invidious/piped frontend, so you’ll need to find an instance for one, but it’s on the app store or can be sideloaded.
There’s that and uYou+/uYou+ extra which needs to be sideloaded via AltStore or other methods, but doesn’t need a piped or invidious instance and accesses YouTube directly
