Fully Kiosk: "Blocked software update"

I wish I had not updated Android on my Samsung Galaxy A9 HA dashboard…

Fully Kiosk now shows an annoying overlay which prevents dashboard usage “Blocked software update”. A toast briefly shows “Software update blocked by kiosk protection”.

If I log in to the admin portal and unlock kiosk mode, all is well for a while. But the problem returns when re-entering kiosk mode and the dashboard becomes unusable.

Have tried disabling auto blocking mode. Clearing Fully Kiosk storage data. Whatever is the update it speaks of?

Thanks for any help.

Got the same issue. Did you manage to find a solution?
