I posted many months ago that the Edge mobile browser blocks widgets from itch.io - I also reported it to Microsoft.  This continues to happen and it is the tracking feature that is blocking the widgets.   If I allow sites to track me - then the widgets will display.  If I disable sites from tracking me - then the widgets won't display.

However, on Firefox, even with tracking disabled - it will still show the widgets.

On Edge PC desktop, even with tracking disabled - it will still show the widgets.

Only Edge mobile it treats them differently.  Is there anything in the widget creation that can be changed to overcome this? Or a way for the widget to just revert to a link if it's blocked?

Because I suspect the majority of Edge Browser users on their cell phones are unable to see the widgets - they're blocked by the default settings.  You have to manually whitelist the site, or go and change the settings away from the default tracking settings in order to see the widgets.
