@leocg Oh, I see. It's embarrassing

There is no "Advanced Synchronization Settings" button, and in the synchronization settings, "Please wait…" You will only see the message.

It works well with the stable and beta versions. Only the developer version has this issue.

The current problem is that there are more than two workspaces and there is one tab remaining, and if you close this tab, the current workspace will be closed and you will be moved to another workspace.

This requires unnecessary work, so to prevent this, you need an option to keep the current workspace even when you close the last tab.
