Is there a way to retain tables that contain default data (roles, job functions, error codes, screen help text, etc.)? That way when you are starting with a fresh database, you still have a functional application.
Downloading the data and then uploading specific data is not really an answer, since Adalo does not do any error checking. It would seem to be simpler if collections had a flag to keep data when copying. Again, then when you are starting with a fresh database, you still have a functional application.
