I am working on an Android application in which I face an issue in Android push notification icon.
The notification icon does not display its content instead displaying in grey colour.
After the research, I could understand that there is a change required in icon for adding transparent and/or white backgrounds since the Android version 5.0
But, my problem now is that I am unable to strongly convey my client about this issue as he shared a screenshot of his Realme X2 Pro device.
It seems that sometimes the device displays in right manner but sometimes not. Please help me find out the solution.
