My app’s URL: https://smartcryptoapp.glideapp.io
I have once changed my app icon but still the old favicon.ico is displayed.
I believe it is working as designed. The icon will not change when it is saved on you phone. You might try to delete the app and reinstalling on the phone.
Even after doing that it’s still not changing.
I don’t remember the steps, but you also have to uninstall the app, then clear it out of your browser cache, or something like that. Those settings are imbedded in the browser somewhere.
Thanks for your reply guys! I see that I was not that complete… Hereby a screenshot of what is happening, the code says that both favicon icons are loaded, of course one (the old one is displayed) this is only happening on desktop. So it will be a minor issue to me…
Do you mean uninstalling the app in glidapps, what will uninstalling the app do with the URL that I used will I be able to use it right away. Or did you mean uninstalling the app on the phone? Because that is working fine with the new icon.

I meant uninstalling from the phone. You might need to clear your browser cache on your desktop.
Happened to me as well. Clearing the browser data solved my issue.
Dear all, After cleaning cash of both my desktop and mobile browser I still get the original icon in the app and not the one I made. In the app creator I do see the new icon everywhere. Does anyone have an alternative option to get the own design in the downloaded app?
Thank you
I haven’t done it in awhile, but I remember uninstalling the app as well as clearing cache. I think sometimes changes will eventually migrate down, but I can’t verify that. I only have experience with Android.
Post a couple of screen grabs and a link to your app… I can share a screen back to you to see if it’s just a local device issue or something more serious… if you like.
