For some reason I can’t click on your image link. Can you post it in the comments?

@bdonvr@thelemmy.club found the solution! Just needed to be installed from Chrome instead of Firefox.

Good idea, I didn’t think about installing from another browser to change the native version’s experience.

Edit: Installing it from Chrome worked! The icon actually shows the wefwef icon now too, which the Firefox app did not. Thank you!

I checked, and both the browser and local ones are the same version. Maybe future versions will fix the problem. Thanks for your help!
