When I open the Google Play store app, icons are missing in the app listings:
This happens only to the Google Play app, where it happened from the very beginning, right when I'd bought the device (i.e. it didn't start only recently). I don't encounter it in other apps. Also, when visiting the Playstore with the device's web browser, there is no such issue: here all images are displayed fine, so it shouldn't be a network/firewall issue.
The device in question is a Note Edge running Kitkat (4.4.4).
Any idea what could cause this, and how it can be fixed?
