[CMP] Sometimes doesn't show gdpr from Admob UMP

[ab-rdarts]

MAX SDK Version

12.1.0

Device/Platform Info

iOS 17.2 or any other

Current Behavior

We have unexpected behaviour with new CMP Terms flow. Sometimes application doesn't show Google UMP Gdpr screen during applovin initialisation. Also mediation debugger shows CMP = none. Sometimes it shows after reinstalling application on the same device.

Experiencing the same issue

as I see Unity plugin has the same issue https://github.com/AppLovin/AppLovin-MAX-Unity-Plugin/issues/328

[PalliativeX]

In my case I cleared the game data after the install out of habit, which seems to clear some prefs required for the CMP (but that's only by default for non-GDPR, without VPN). The main issue was the setup of Admob Consent window (I was provided the Admob App key), which didn't show the CMP window with GDPR debug mode or German VPN. When I used my own setup, the issue resolved.

Speaking about Applovin setup, I enabled MAX Terms and Privacy Policy flow, provided a Privacy Policy link and added AdMob to mediated networks (not sure that it will work without using it).
