If you see an error when trying to invite someone to your Vinyl account — whether it's a message about the email address already being in use, an account conflict, or a generic error on submission — this is usually caused by a previous account setup for that person that didn't complete properly.
This isn't something you can fix from your end, but it's a straightforward resolution for our support team.
What to do
Contact support with:
