- Seems like regression, but I can't test earlier versions because of the thrown package errors

    You mention the resolution of the issue in 2019.2.22f1, but it's not available on the downloads page... Please make this version available to us.

    Why is this not mentioned in Known Issue release notes for Unity 2019.2.21?

    Is there any update on an ETA for Unity 2019.2.22?

    I need that fix for 2019.2.x, because 2019.3 does not contain the very fast (old) GUI Layer and I should write again the game UI.

    Is there a workaround? or do I just have to install the latest unity?

    When is this fix to arrive in a production version? between this bug and OpenGL shader bugs (this has since been fixed) we've been unable to compile a working build for Android since Sep 2019 (v2019.2.4), every version since has had show stopper issues. It'd be great if this could be stepped up and back ported to a 2019.2.x version as I'm quite concerned that 2019.3 is going to bring a fresh round of issues with it. Will the fix at least be shipped with the first production ready version of 2019.3? Sorry but having to wait 4 months to 'maybe' be able to compile a working android app is quite frustrating.
