How to Reproduce

We are using latest Applovin SDK v8.01 Android v13.0.1.
This issue first started to appear with updating Firebase to v12.5.0.
There seems to be an issue between both SDKs mainly Safedk.

Reproducible in the demo app?

Not Tested

Hi @JimRaid, what Ad Review version are you using?

[JimRaid]

Hey @NanaAmoah, I'm using the Unity Package where can I find the version? There is no Ad Review in the integration manager displayed?

Edit: How do I update Ad Review SDK there is no Documentation of this?

[NanaAmoah]

@JimRaid for Unity, by default, Ad Review gets automatically updated once you build your project. You can verify the version of Ad Review in the Mediation Debugger under MAX > Ad Review Version.

[JimRaid]

Ok we are still on v5.6.4 that explains it, but I have the issue that new builds don't have an updated version.
I did a "Force Resolve" with the External Dependency Manager. Any way to make it use the new version?

[NanaAmoah]

@JimRaid We included fixes for these ANRs in v5.6.5 and v5.6.6 of the Ad Review SDK. Did you see any errors in Unity when building the app?

[JimRaid]

@NanaAmoah I didn’t encounter any errors during the build. As a workaround, I manually edited the AppLovinProcessGradleBuildFile class and set the version number from "+" to "5.6.6". This forced the build to use the correct version, and everything worked as expected.

However, when I change the version string back to "+", it automatically reverts to v5.6.4 during the build process. I’m not sure why it fails to pull the latest version.

I’ve submitted a hotfix now for my app, so the issue is hopefully resolved for now. Still, I’d appreciate understanding how to make the Unity package consistently use the latest version.

@JimRaid We haven't been able to reproduce the issue you reported. Could you try clearing the library and/or Gradle cache to see if that fixes the issue?
If it doesn't, could you try reproducing the issue in our demo app here and sharing the modified project with us so we can investigate further?
