Message - This app has reached its updates limit

Hello, friends! Please help me. When registering a new user in the app, a message appears: “This app has reached its updates limit. Please contact the app owner to resolve this issue.”. As far as I understand, registration is available for 10 users on the free plan
I have 3 registered users in the application, the application does not allow anyone else to log in.
The application is public and the roles are not distributed. I also tried to delete the column with the pianos - unsuccessfully. I am attaching screenshots. Please help me figure it out
