Right now the iOS mobile app and browsers does not support viewing the webresources added to a PCF

We've built a custom PCF that shows Account records in a Map component, we used some custom icons that are saved in the environment as WebResouces. These icons are not shown when using either the D365 Sales mobile app or the Power Apps mobile app only when using iOS devices. Everything is working fine on Android devices

The issue is on a Modal Driven App (D365 Sales standard app) when using a PCF.

This should work on every devices
