Hi Igor,
Thank you for reaching out to us.
We've tried our sample app for interstitial in our end, and upon checking we're able to load ads in our end. Can you confirm if you didn't change the ad unit id? Our sample ad unit id for interstitial is "ca-app-pub-3940256099942544/4411468910" which we used in our testing. If the error still persist in your end, can you provide us your project file that used where this is reproducible?
If the file(s) you are looking to share are less than 25mb in total you can attach them to this case on your next reply. If you are having trouble attaching your file to this case or if your file(s) are larger than 25mb, you can share your files with me by performing the following steps:
2. Fill out all fields, and attach your file(s).
3. Please reply back on this thread when you have uploaded your file(s). Please do not share this link.
