Starting with AGP 9.0.0, optimized resource shrinking becomes the standard behavior for any project that has the resource shrinker turned on.

Hello @Kevinrob,

Thank you for bringing this to our attention.

We have investigated the issue and identified a solution, which is planned to be released in the future.

In the meantime, could you please test the SDK version 1.0.0-test260203 to confirm that it works as expected on your end as well?

Thank you very much for your assistance.

Best

Hi @luiscosta,
This works well with version 1.0.0-test260203 👍🏻

The issue will be left open until we release it. (Closed by mistake)
