Unable to access app, blocked by plan select

Hey there, I'm not really a power user, but from time to time I check the stats & charts. Lately, I noticed that my "team" dashboard was not visible to me, but was still visible to a friend I was in a team with about a year ago. After the latest update, I can't even use the app anymore, even though I'm on a paid plan.

"My guess is that some old hooks responsible for cleaning up relations after the team was split didn't perform all the required actions, and some permission connections were left behind, allowing my friend to monitor my dashboards from his account."

I'm happy to provide more information if needed. Thanks!
