Sorry to post in this (slightly) old thread, but after submitting a new version of my app compiled with the newest AppGameKit Studio to the Google Play store (submitted 25th Feb 2023) I heard no complaints from them... until now. They have just messaged me with basically the same issue and a threat to remove the app on May 17th if it isn't fixed. This is what their email says:
Quote: "We've identified that your app or an SDK in your app transmits device identifier(s) from children or users of unknown age that do not comply with our Families Policy.
- These identifiers may include but are not limited to Advertising ID.
...
Apps that solely target children should not transmit the following:
Android Advertising ID (AAID)
SIM Serial
Build Serial
BSSID
MAC
SSID
IMEI and/or IMSI
Apps that target both children and older audiences must not transmit the listed identifiers from children or users of unknown age."
I definitely have
SetAdMobChildRating( 1 ) in my code. Unless there is a quick fix anyone can think of it looks like I might have to remove the app from the Google "Designed for Families" scheme, which would be a shame and could dramatically shrink the target audience.
