I have not seen a less friendly interface before.
the text of the errors is absolutely not informative.
guess what is wrong - impossible!
choosing traffic lights from google capcha for every move is disgusting
I also had to guess to fill the field music tags to ask this question
Solved! Go to Solution.
If you've still got this problem there's a fix that helped me perfectly.
When adding your "Spotify Playlist Link" instead of just pasting your Spotify Playlist URI do this:
Right-click the name of your Spotify account on the desktop client, click share and copy Spotify URI, paste the URI into the "Spotify Playlist link". When this is done copy your playlist URI as well and paste that besides the account URI in the "Spotify Playlist link" tab.
This is what it's gonna look like with my URI's as an example.
The last step is to remove the Spotify part from the second URI you pasted in, so it would look like this.
I will attach a picture for you.
