I am happy to share this kind of things as your opinions help me improve more and more!
About your issue: I checked the code a lot of times and couldn't understand why ads sometimes show and sometimes don't when you close and reopen your game. There are three possibilities:
- I am missing something (

);
- The AdMob SDK Stencyl is using is outdated (4.x vs 6.x). Perhaps this old SDK version has some bugs or incompatibility issues with newer devices since it was released before Android 4.x.
- There are some underlying issues when integrating AdMob in Haxe NME. Jon himself said he was forced to choose an older version of AdMob SDK since he got some errors when implementing the newer versions.
Thanks for sharing your experience!
If someone has any ideas, I am ready to listen!
