Hi Stumbler! Hatchling here to assist you with any concern you may have regarding ads 🐣  
  
This setting needs to be changed in device settings: 
In your phone (not in game) go to Settings > Privacy > Advanced > Ads and toggle off “Opt out of Ads Personalization"  
  
The path may vary depending on what device model and operating system you are running.
 
Keep on stumbling!
