    I'm having the same problem. We're experiencing a physical degradation caused by Unity on some mobile devices, and we're getting stuck now because Google requires 64bit support.

    Same problem. It is important because 64 bit support is enforced by Google to publish the app.

    We have the same problem. Since this is a very critical bug for our game, We kindly request an immediate correction.

    Same problem. It is mission critical because Google no longer allows putting apps without 64 bit support on the app store.
