all homekit scenes delete themselves almost monthly

please help, its such a waste of time setting up all my scenes again and again, especially since this has happened to me almost 10 times at this point, a few times they even deleted only a couple days after re-setting them all up again. how are you guys dealing with this?

if i could edit all the lights at once, like the color or intensity of all the lights at once, then i could at least deal with that, but im left having to individually control all the lights manually, its so frustrating. i cant return all my smart bulbs at this point.

This is unusable. I'm using a macbook and an iphone interchangeably to control homekit. Everything is up to date.
