Re: Trying to link 2 youtube accounts to 1 AdSense 1 with 500 error and 1 disabled
AdSense in English
I have an active account: Working with AdSense :
Yes that is the account with the error. The new youtube account with the email linked to the new adsense. I just opened the new adsense yesterday. I also have 3rd party access enabled for YouTube.com.
