After both updates that were pushed recently, the app icon disappeared from my phone’s screen and had to be re-added from the app drawer.
I’m using a Samsung Galaxy Note 4 with Android 6.0.1.
At first I thought it was because the icon image had been changed to the new logo, but when the fix was pushed, it happened again.
I have no idea if this is a bug or not, but I thought it was worth mentioning here.
It isn’t really important.
