A. Check if the app has an option to remember your login credentials. Go to the login screen and look for a checkbox that says 'Remember Me' or 'Stay Logged In'. If available, select it before logging in.
B. Ensure that your device settings allow the app to store data. Go to your device's Settings > Apps > Nowsta > Storage, and make sure that 'Clear Data' is not selected. If it is, you will need to log in again each time.
