Following discussion on IRC channel, I post here:
The problem is, Flurry version 4.2.4 uses IDFA and people already report their apps were rejected because of this.
People also say that Flurry version 4.3.1 has this problem fixed.
Docs on analytics are outdated, saying version 4.1 (iOS) is used. From what I can see in the Flurry console, Corona plugin "CoronaProvider.analytics.flurry" actually uses version 4.2.3
I don't know if this version uses IDFA too, but it well may be as it is close to troublesome 4.2.4
Corona staff, could you advise?
