Everytime we restart SourceTree it appears the warning on remote icon as the image below.
We are connected to our Bitbucket server so, we use active directory integration to log in. As community people said, we use the warkaround that implicates to update connection account in repository settings. This not affect program usage, but it is very annoying why everytime we restartcomputer, it appears again and generic account is setted by default in settings.
We are working on 3.3.4 that Windows version of SourceTree, that is not listed in your affect version comboBox.
