I have nothing more to say other than I can't seem to download macOS Catalina beta... it's not available apparently?

I even followed this link, which shows the update in the app store: https://apps.apple.com/gb/app/macos-catalina-beta/id1455661060?mt=12

I have the Feedback app installed and everything, I've restarted my mac and it's the 2019 mac so it's not like it won't be supported. Any help?

You can check if you have a non-standard update source:

defaults read /Library/Preferences/com.apple.SoftwareUpdate CatalogURL

If CatalogURL does not exist, that's OK and the standard situation to pull from the non-beta updates. To force a beta source, you write this key (as root if needed with sudo)

sudo /usr/sbin/softwareupdate --set-catalog https://swscan.apple.com/content/catalogs/others/index-10.15seed-10.15-10.14-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

Choose About This Mac > Software Update. Wait a moment. An item for macOS Catalina Beta appears.

You can request an update as well from the command line just as you set the default:

softwareupdate -al

Change the lower case L to a lower case I above and prepend sudo to download and install all updates.

For me I was stuck with a terminal that refused to open. I ended up deleting the previous beta installer I found on the second page of the launch pad. Once I deleted it and then re-ran the macOSDeveloperBetaAccessUtility.pkg file again I was able to download and install the newest beta.
