Architecture type for available apps

[qtotter]

I could easily modify *.img files with the scripts, and install WSA with Gapps.

I guess it's the architecture info for available apps, but only a limited number of apps showed up in Play Store. I checked the missing app that I wanted to use, and its architecture type was categorized as "universal" on Apkmirror, not built each for arm64/x86_64/etc. It shows up on intel-based Chromebooks. I could sideload the apk, and it runs without problems. Is it an issue with OpanGapps or one from the modified images?

Thanks.
