Hi @rami4625
We had the feature but removed it because when someone uses the switch button to dark or light, we cache it and serve the webpages as per user preference until the next visit to the site.
You know, it would be boring to change pages to dark or light every time a new page load.
We would like to know why you need this feature. If it’s important for a good reason, we will bring that back in the next release.
