Problem with Android 14

[Maiquel Ferreira]

I recently launched my game on the playstore and all Android 14 players are reporting that the game doesn't open or stays on a black screen, It appears to be an SDK initialization issue, error below.

Hi,

I have tried running a Google sample project with unity version(2022.3.22f1) and Mobile Ads SDK version(9.0.0) in Android 14 and unable to reproduce the issue. Could you please confirm the same from your end. Kindly provide the below information for further assistance:

• Unity editor version
• Mobile Ads SDK version
• Sample project which replicates the issue (if possible) 

This message is in relation to case "ref:!00D1U01174p.!5004Q02s0Gch:ref" (ADR-00228830)

Hi,

We have tried running Google sample project with mentioned Unity Version 2021.3.25f1 and Mobile Ads SDK Version 9.0.0 and able to load the ads successfully. We need detailed debug information from a device where it's observed in order to actually make any progress in diagnosing this. Kindly share a sample project which replicates the issue for further investigation.
