i can not see my subscription and watch later and playlist... i just get a box with .. to go back

This solved the "..." for me:

Go into your home menu -> Choose to create a sub menu for youtube -> Choose Sign In -> Then before it tried to create your submenu it will ask you to activate YouTube (as per usual twice) -> After that, enter YouTube add-on as per usual. Ignore the fact that you think you are already signed in. Pull up the submenu creator for your skin and create a Sign In submenu, that's all it takes. The addon will still not update it's setup from the settings application (wont display the various lists just the ones already set.) But at least you can now access the things you want to again. I tried deleting the addon_data folder and it didn't work. I cleared everything in Kodi folders related to youtbube or that had youtube in the filename, it still remembered my settings and couldn't figure out that I needed to log-in again. So force the log-in.

Worked for me, watching YouTube as we speak, just wanted to share.
