I am having the same problem!
I have logged in and out and it is still giving me the same error message.
Please let me know if there is a solution!
hello. i cant save youtube videoes to favorites! get an error
"There is a problem communicating with youtube. try agein later."
is it a fix for this or do i have to wait for apple to fix this??
There is a fix for this. Search the forum. You basically have to go to youtube.com with your desktop browser and adjust your "Activity Sharing" under account settings to include "Subscribe to a channel" and "favorite a video".
