I just updated my HA and all of a sudden my tablet view in fully kiosk shows an error “custom element doesn’t exist: horizontal-layout”. It works fine on my PC and also works fine on the tablet when I simply open HA without using FK. It’s running on a new Samsung tablet and I checked to make sure HA, FK and the Android web viewer were all updated and they are. Tried restarting the tablet and still nothing, can anyone help?
This happens to me every update… a pull down gesture on the tablet dashboard to reload the page usually cures it.
