DraStic

My Kid has a KURIO 7S. I've install a paid version of DraStic from the Google Play store.

DraStic works fine with a number of Pokemon games on my parental account, but fails to start-up correctly on the kids account. The DraStic window closes after a few seconds, with a message like "failed to start".

If anyone can help, thanks for your time.

How does the user management on that tablet work? Are the 2 accounts tied to seperate Google accounts?

I could see 2 possible problems, one being the Google Play licensing, which ties the app to the account it was purchased with, the other some permission problem with your kid's account.
Is access to storage limited on that account?

Can you tell us anything else about the error?
Does the app seem to crash? Is the error message from the system, or from the app, and what does it say exactly?
Do you see the start menu before it closes?
