Can confirm trying to create repo creates pop up 👍 And when I'm in repo, can create branch 👍 However, when I make said branch, then try switching back to another branch, I cannot seem to do that. Is this issue present in your local version?????

[joel-clarke]

Yup, I am on Windows. I updated the branch to the most recent version, the changed functionality seems to be working as expected for me and I can change branches. @lukethompsxn if you could retest the change that'd be great!

Yup, I can change branches, not sure what was going on there
