After selecting a desired branch I couldn’t download the code from the selected branch. For example if I switch the branch from master to dev-branch and click Code > Download ZIP, the generated zip file is from the master/default branch. Normally I could generate the zip file from the correct branch.
I think this issue is fixed. It is working perfectly now. Thanks for reporting and thanks to GitHub for fixing this issue.
… Can also confirm as fixed; thanks to those responsible !
