Screen refresh

I have 2 Fire HD tablets and am using Lovelace. One tablet auto refreshes and keeps up to date but swipe down from the top doesn’t refresh it and the other doesn’t update on its own but swipe down does refresh it. Both screens are activated by the camera. This might well be just settings but I can’t
remember where to find them. Any suggestions or info on where the relevant settings are would be useful.

Sorted, one had HASS app and the other had Wallpanel.
