Starting with StellarMate App v3.0, StellarMate switched to a different management server for license data. If stale license data is encountered, you might receive this error.

The data can only be refreshed after signing in again to the App. Therefore, there are two approaches:

1. Go to Settings --> Logout and close the App and sign in again to refresh the data.

2. Completely uninstall and reinstall the App to ensure there is no residual cache left that might affect this issue.
