csavalas, there was a quick fix from Appodeal - now you can build on iOS just fine without a crash.
chodongwon82, just to be sure, you’re not using those two code snippets simultaneously, right? As stated @ https://docs.coronalabs.com/plugin/appodeal/, the first one is for accessing Appodeal in a legacy mode, while a second one gives you access to the new modular system (+ beta functional, if you include .beta to adapters name).
Anyway, I tried to show a banner with your build settings on our sample and it works both ways: with or without a test mode banners are showing up as expected. Make sure that you’ve set everything up correctly (like, Appodeal’s dashboard and stuff) and if you still won’t see banners - write to Appodeal support, they’ll help you with that.
In the mean time, we can look if everything’s ok with your code. For that you’ll need to submit a bug @ https://portal.coronalabs.com/bug-submission. Make sure to include a sample to reproduce an issue (just a simple one with ads logic is fine). We’ll check everything and will let you know if there’s something wrong with your code or the issues is indeed in the ads fill, so that only Appodeal support can help you.
