since I had no installs reported on Chartboost, I contacted their support. This is what I got:
Thanks for the email and for letting us know. I took a look at your App and realized what is going on. Corona no longer allows access to required device identifiers in the free Corona SDK. We were surprised when this happened and this is the reason why you're not seeing converted installs and earnings. My understanding is the a recent update to the Corona build removed the ability to obtain a device IFA.
Until Corona allows access to the Identifier for Advertising, you may want to look into upgrading to corona enterprise and using our native SDK or contact Corona with feedback requesting access to all device identifiers. Another option is to utilize a pre-2169 corona build and resubmit to Apple as those versions should allow you to obtain the IFA. If you'd like, I'm more than happy to test and ensure that converted installs are properly tracked with the pre-2169 build.
Is that right? Would Apple still accept submissions with a pre-2169 build?
Are the "natively supported" ad plugins (like Admob or Vungle) affected as well?
