I just spent a few hours integrating in startapp and found a curious behavior. I have it set to only display an interstitial ad on a particular transition which is working fine. However, I noticed ads are displayed whenever my app resumes from a suspended state. startapp.show() was not called and I see no callback about an ad being shown occurring to the listener I registered. The startapp API is rather simple and I don't see any way to prevent this behavior. Very disturbing.

Has anybody else seen this behavior? Do other monitization plugins also behave this way?
