Oh no! This is probably a side-effect of me fixing (WWW-1393 Installer feeds failing) combined with a bug that never showed up in Rhino before, because this bug was broken for so long.
I just logged: (RH-63356 Rhino Installer blocks while asking to update)
I think it’ll be possible for me to fix this in a future Rhino, as well as update my fix to WWW-1393 to only return update notifications when newer Rhinos are installing.
As a side note, I recommend you install keep up-to-date, and install 7.4, as we’re fixing lots of bugs that were in Rhino 7’s initial releases. For a long list, see Rhino 7 Service Release Available.
