Have you guys tried linking a different account? I had the same problem originally. Wouldn't link up but I could still upload the videos to facebook. Then all of a sudden it started working by itself.
My account used to be linked, now it says link YT account. Not sure why it stopped working since I have successfully uploaded a video before.
Forget email, use the online support link here. I have had the same issues with email but when I used the online support I CANNOT fault them. Had to try a few different soloutions to my problem and it took about 30/40 mins. Click the online support button!
im having the same problem.......when i try to link the account, it asks me to grant permission (which i do), then it says i dont have the channel which i clearly do beacause it is taking me there!
i have the EXACT SAME PROBLEM, it says This account already has a username and channel. which irritates me soooooooo mush
I had this problem. I tried using a different computer, and then I was able to successfully link my accounts.
I get the same problem and its anoying it just keeps telling me to create a youtube channel when i already have one
