Clear and concise description of the problem

I am using the app and encountered an issue when trying to set up two space. I want one space to be local and the other self-hosted. However, the app currently forces a complete logout and requires changing the sync type each time.

Suggested solution

Implement the ability to set different synchronization methods for specific space.

Alternative

Provide a simpler way to switch between accounts without needing to fully log out or make other complex changes.
