Limit users Pro App

I have a Pro App with 25k of rows and I dont have reached this limit but some new users are reporting me that they cannot enter in the app because it has reached the limit of users (semms in 3.000).

Is that true? Pro Apps has 3.000 users limit?

No, as far as I’m aware there is no limit on the number of users.

Are your users actually seeing a message that indicates this?

What is your solution?

This message should only show for free apps with password authentication. Could you give me a support link to the app, please?
