YouTube Not Working

When I started setting up Youtube, I got this message "You must enable two applications so that YouTube is functioning properly”. How do I fix this?

It should issue instructions immediately after that message if you didn’t cancel the operation.

It says to log in twice.

So what is the problem?

In the past, I’ve activated it twice, as per its instructions and after playing a few videos, YouTube stopped working and my  TV froze. I reinstalled OSMC after that and here I am. I’m just worried it’ll freeze up again after playing a few YouTube videos. But it’s working now. So, I guess it’s fine, at least for now.
