Hello, We have an extension that is accessed by 2 users via the 3CX Android app. Basically it is our "on call" extension and one user monitors it some days and the the other on other days. We are letting one of the users go and need to make sure they can no longer access the extension. However, we need the other user to continue to have access. I thought I would just change the registration password and have the continuing user just update the app but it appears when I do that, the 3CX app gets the new registration information whenever the app is started. If anyone has any suggestions I would appreciate them.
