The problem is recurring on my device even after updating to miui 14. I can be using any theme I want without any problems as long as I don't activate the second space, because when activating the second space the device absolutely does not accept a non-standard theme and the only way to solve...
I have a problem with the themes app, I activated the second space tool and the theme I used that was downloaded from the store was reset to default, and now whenever I install a new theme it is reset to default automatically in a few minutes.
