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
This is a known issue we've fixed for 3.1. We're going to move that to beta testing soon but I don't have a firm ETA for delivery. The workaround is to go to the Remotes section of the Repository Browser and then filter it using the search field to what you'd like to clone. Clicking the "Clone" button should pop up the dialog and behave as expected. Apologies for the hiccup.
