indiDing Hi! As @mythodical very correctly stated, all you have to do is:
- Long-press the notification that says "Sandboxed Google Play is running"
- You'll see a "turn off notifications". Tap on that.
- You'll see different notifications. You can disable the "Sandboxed Google Play is running" one, and click "Done" on the bottom right.
You should be good to go from there!
