Investigating it now...

[marcojak]

I've tested the MAUI version for .Net 8 on an Android phone on the latest version of the plugin and it works as expected.
Of course the automatic reload of the ad, doesn't work as there is no network but I don't see any black screen.
If you still have the same issue, could you provide additional info?

[AmperLab]

Thank you for the update. It's worth noting that the error occurs specifically on a physical Android device.
I've also conducted testing on an emulator and did not encounter similar issues.
I also want to mention that I upgraded from an older version of the plugin to the latest one, and the issue persists even after the update.
Physical android device has API 33

[marcojak]

I've tried it on a Google pixel 7 pro with android 14. What I've done: 1) load the interstitial 2) show the interstitial 3) go into airplane mode. 4) close the interstitial clicking on the X I've tried several times and it always worked. If there is anything else I can do to reproduce the issue, please let me know.
