Hi.
I use sourcetree for windows version 3.3.6 with git for windows version 2.25.0.windows.1.
If you have a large number of branches (about 20), double-clicking on a branch to switch it will not cause SourceTree to automatically update the display.

If the number of branches is small, it will be updated automatically, but often you need to press F5. It behaves as if not switching and is very confusing.
