Yet somehow when I click Preview and try to input some dummy data and click “Save”, the data doesn’t appear in my App Data afterwards. Am I doing something wrong?
I got the answer myself after Googling - the newly saved data doesn’t reflect instantly in the app database after saving. You’d need to wait a bit and refresh before it appears.
This point wasn’t mentioned in any of the guides so hopefully someone who had the same problem will get the answer here.
