Browser mod: camera entity from wall tablet disappeared

Hi guys,
can me someone lend me a hand in why my camera entity in browser mod disappeared from my dashboard tablet? 2 days ago for sure existed, today observed the message “Entity not available camera.tablet”. I’m using the tablet with Fully kiosk, till now were no problems.
Interestingly, if I start HA app without Fully, the tablet camera entity exists.
Thanks in advance.
