I noticed that when I uninstall my app via Gadget or directly on the Shopify store the data still persists. I'm reading from Shopify review process that this must be addressed and data has to be removed that is related to the store that uninstalled the app.
So my questions are:
1. Is there a built in way that Gadget can accomplish this or is this a manual build?
2. Is it that important to get app approval?
