Devices windows app and Mac Finder do not show iOS beta updates

I am in the public beta. On my iPad, it shows that RC for 17.4 is available but can’t be installed because space is low. I have to use Devices or Finder to update. When I connect my iPad to my pc or Mac both say 17.3.1 is the latest version…even though the iPad says RC 17.4 is available. So it won’t update.

This just started recently. Any suggestions?
