Apex Theme Style selection across apps / user preferences

Hi, folks,

in our company we have about 50 Apex apps, which share authentication, authorization, universal theme, navigation, … – this is working nicely due to the subscriptions.

Now we want to allow the users to select their preferred theme style (e.g. light mode vs. dark mode). So we enabled the attribute "Enable End Users to choose Theme Style".

After that a user can open the dialog and choose his preferred theme style, but when switching to another app this information is lost. The user has to repeat his selection for every single app to get a seamless experience. This behavior of our apps is not acceptable.
