If doesn’t matter if I open it in the app, in the mobile browser, or if I just put a smaller screen on the laptop until it displays the mobile version.
I am not using so may icons in the desktop version so I am not sure if there can be similar issues on that one or it is just on the mobile view.
Are you using bindings to display these icons dynamically?
If you are, the issue may be coming from using concatenation in your bindings. Here’s a section of the docs that explains how to avoid that: Icon | Documentation
If that doesn’t solve the issue, could you create a bug ticket here if you haven’t already?
