When I select the checkout in Sourcetree link in Bitbucket, it used to launch Sourcetree and provide me a dialog to checkout a branch. After doing a Sourcetree update, it still launches sourcetree successfully, but never provides the dialog to checkout the branch. No errors are shown at all. Did the feature go away? Seems odd to me.
Sourcetree version 3.0.1 (205)
I'm on OSX: 10.13.6
