Hi Stumbler! Hatchling here to assist you with any concern you may have regarding ads 🐣 
We are sorry to hear that you haven't been able to watch advertisements.  

However, ads depend on how and where the advertisers want to show them, so unfortunately if there are no ads for you to watch it means there are no advertisers in your area. 
You can always try to change your location using VPN to troubleshoot this issue.

Please keep in mind that certain device types don't support ads at all.
Keep on stumbling!
