Actual result: Texture with ASTC_RGBA_4x4 texture format fallbacks to ASTC_RGB_4x4 and 'Texture creation failed. 'ASTC_RGBA_4x4' is not supported on this platform. Use 'SystemInfo.SupportsTextureFormat' C# API to check format support.' error is thrown

Hi,

I am the original reporter of this issue and have been keeping track of this page and the original ticket as well for progress. I came back today to see the Resolution Note under the ticket description, and that it mentions an api update that should resolve it automatically. Can you speak more to this?

I also notice, per the description in the ticket, that the issue is reproducible in the latest 2019 LTS and 2020.1.6. With a fix inbound, would you be able to say what patch release for 2019 LTS the fix will be in and when we can expect to see that build? Thank you in advance for any and all information, as it will be extremely helpful.
