Ad Mob Interactive Interstitial Hangs Ionic?

Has anyone experienced this? I have an ad mob interstitial ad on android with crosswalk. (I have not encountered the ad type in question yet on ios)

if a non-interactive ad runs, after closing the ad, everything is fine.

If an interactive ad runs (specifically Game of War ad where you can play 2 moves of building - might be others but that’s the one I get), when I come back to game, ionic is locked from an input perspective. I can’t press anything or scroll or such. A background service with a websocket also appears to get frozen.

There is nothing in adb logcat or console logs. Only option is to restart after this.
