I wanted to do that, but then I found a paragraph in the adsense guidelines that you are not allowed to show those ads in apps.
Although that was nearly 10 years ago. Perhaps they changed the rules post-Android
After your post I tried to find the paragraph in adsense rules that does not permit ads in windows apps (because in android apps it is permitted) and I did not manage to find such rule after 2 hours of reading.
Even if google ads are not permitted in apps i am still interested because there are more ads from adsense that i could embed so if someone can please help us do so!
And if i am able to embed an html page then it is in not in the actual app so the imaginary rule won't be broken!
