WallPanel with AppDaemon - No icons with Android 4.4.2

Hello,

I have an ASUS MeMO Pad 7 (k01a) tablet with Android 4.4.2.

I use the latest WallPanel app from the Play Store and the latest AppDaemon but I cannot see the icons on the dashboard.

I can see the icons properly on the tablet with the Chrome browser.

Could you help me please what am I doing wrong?
