Describe the bug / error

We have a couple SPFX web parts that work just fine on mobile browsers (see images below) When we try to use the SharePoint Mobile App, both Android and iOS, they just wont load.

Is this a normal behavior? Are we missing some "setup" to make them work fine?

Steps to reproduce

Expected behavior

SharePoint Mobile App would show the custom spfx web parts correctly
