Question: why do some ipad homepage icons have black backgrounds
A couple of the icons on my ipad have black backgrounds
1. What causes this ?
2. Why are these few the only ones affected in this way ?
3. Does anything need to be done to correct this ?
4. If so, what exactly needs to be done to correct this ?
I am using an iPad A1474, which I have used for 2 or 3 years.
Any help would be appreciated.
iPad Air Wi-Fi, iOS 11.1
