The app needs an enable/disable function. If we need to disable samples and enable it later, there is no need to delete the whole app. That's a waste of time.
I'm really sorry about the bad experience. For now, we have the option to choose which theme should have the sample function.
If you want to disable samples, you just need to disable samples from your live theme and no need to delete the whole app.
I will follow up with you via email now and make sure we do everything we can to produce a 5 star experience for you.
