Mac OS Public Beta Download Issue

[cgordonn]

Long time iOS Public Beta user here. With the implementation of iMessage on iCloud, I wanted to take advantage of this new feature on all of my devices. I have the current iOS public beta installed on all of my iDevices and have attempted to install the current Mac OS public beta on my MacBook Pro. I have installed the public beta user profile on my MacBook Pro and have followed all the directions to install the current Mac OS public beta, which is 10.13.4 beta 3. However, when attempting to show the download, the system says no current updates available. I have rebooted my MacBook per Apples public beta install instructions and it still shows no updates available. I am wondering if anyone else here has had this issue and possibly some guidance on how to resolve this. FYI, Apples support options on this matter are non-extant.
