I would suggest just use GitHub as the platform for communication, just like the old galaxy code base, rather than jumping among 3 or 4 different websites, each requires its own account registration, for different stuff. The developer/user experience isn’t very nice this way.
Issues are disabled in that repo. The “About” recommends “Issues on https://forum.ansible.com” (as shown in the link preview above), but that seems to be a bad recommendation since I haven’t seen much feedback on Galaxy issues reported here on the forum (other than: Galaxy is broken) so far.
