custom svg icons in Model-driven app
I have a solution with web resources (see attached) stored as SVG files (okres.svg and skupina-black.svg). These icons are used in a Model-Driven app for custom tables. For many months, these icons were displayed correctly, but a few days ago, the icon okres.svg stopped displaying. When I edit the Model-Driven app in the navigation section (left side), I can see the icon, but when the app is loaded, the icon does not display. I have tried clearing the cache, reuploading the icon to the web resources, and publishing all customizations, but without success. The issue is the same across three different environments. As I mentioned before, it was working for many months, so I suspect there might have been a recent change in the requirements for SVG icons. However, I cannot figure out what might be causing the issue. I would greatly appreciate any hints or tips regarding custom SVG icons or advice on how to use SVG icons in Model-Driven apps these days.
