So I have had a ton of challenges along the way. My current state is that my game was rejected by apple last night. I have integrated the Appodeal SDK and it had included the Yandex SDK in it and Apple rejected that particular SDK. So I've downloaded a new version from Appodeal that has that fixed (hopefully) and the Trixel Rocket game is now back up in the Review queue. This process has been a challenge. The lesson here? DON'T GIVE UP! Keep going. You will get there (and hopefully I will get there). Fingers crossed!
Mine was just rejected for the same reason. Did you end up using the Appodeal beta sdk 2.4.8? W Was the setup the same as in the pdf provided here: https://www.buildbox.com/forum/index.php?threads/tutorial-appodeal-mediation-buildbox.12221/
