It has something to do with the detection script the first time an application installation is run.  For me, the solution was to pick a winget-deployable application that I deploy to all my endpoints, but with manual detection logic (File/Folder/Registry, etc) instead of the detection script.  After that all future installs, even if they use a script for detection, no longer exhibit the delay.

Note that this might need to be done once for a System-mode install and once for a User-mode install.  I am testing the User-mode scenario myself.  But it definitely worked for installs that run in System mode.

I don't have an explanation for why it is like this though, or if our situation is truly uncommon among admins that use Winget to deploy applications made available via Company Portal.
