Unable to Accept Invite

I am getting this issue when trying to accept an invite to a new test version of our app.

****Unable to Accept invite

This invitation cannot be accepted because your Apple Account, xxxxxxxx.me.com, has already been associated to this app.****

Can you help please?

In TestFlight?

I'm having the same issue, this is really frustrating. I've tried removing my account and re-adding. The account is an Admin account. This is holding up all my work.
