When I tap on all apps I always find that Microsoft weather app has a blank blue tile and the same thing applies to Microsoft Groove. I have discovered that uninstalling the app and reinstalling it recovers the lost icon as I did with MSN News. Now I can't uninstall Microsoft Groove and Microsoft Weather apps? How do I solve this problem without resetting my device?
For your information these two apps are functioning well except for this somewhat trivial problem.
My phone is a Microsoft Lumia 640 XL running Windows 10 Mobile
