App Icon Missing on Beta Version installed on Fire TV 4k Max

I have 3 Fire TV Sticks. Two are 4k sticks and work fine. The latest is a 4k Max. When I installed the Beta app it does not have an APP icon. I did see a note (on Fire TV Cube) that this might be an issue with Fire OS and sideloaded app. Is this true on the 4k Max?

Yes all versions of FireOS have this issue
