Works for me. I just don’t have the recommendations on the side.
I a get to anything I’m subscribed to or have saved and hop around fine but the start page is out.
For me, if you know the name of the channel, you can type it in and get results, but it won’t show anything other than videos posted by that channel. However, that’s the only search functionality that I had working. Try to search for some random query and you just get this. Something went wrong message on both the app or web.
