I've tried to add my YT account but it didn't work. Then found this thread and now know why
It should work after the next CORE-update you say. Got any ETA on that?
Thanks.
PS: has something been changed to the forum? I had an account here AFAIK but was unable to login and had to create a new one.
I'm 99% sure I've posted in the past under this name (probably a few years ago though).
