@NathanWalker thanks a lot picking up on this and pushing a release out there - that helps with testing.

testing is actually the reason i kept the MR it in DRAFT, I'm on it and stumbled into a problem when using the updated version with angular. keep looking into it.
did you successfully integrate the new version yet?

Tests (Published version 2.2.0):

Android 12 / Pixel 3a ✅ (Angular and vanilla)
Android 16 / Pixel 8 ✅ (Angular and vanilla)
Android 12 / Samsung M51 ✅
Android 16-Beta / Pixel 9a ✅
Android 15 / samsung s24 ✅

Next thing is to validate with Google that the 16KB requirement is fulfilled.

Also, on Google Play Console, the libraries from this plugin are not shown as incompliant anymore 👍 (virtuall) also Un-drafting the PR from my side :)
