I find this to be even more confusing, Colin.
The Apple ID I use in the app store is one I created decades ago, and is personal. While it is my active ID for the app store, it is not the iCloud ID I use for coordination across my Apple devices. Apple, in their infinite wisdom, has never allowed for the combining of Apple ID’s.
My Trimble ID, which is a business not personal account, uses a different set of credentials entirely - separate email, password etc. It seems to me, the test Trimble ID I created using my Apple app store email, is now divorced from my Trimble ID that I use to “log in to all things Sketchup” through the Sketchup Pro application.
I DO NOT want to “mix” my personal and professional ID’s.
The link you provided above took me to a login page, where I logged in with my Trimble “ClearPlan” ID, not the one just created using my Apple app store email. Note the screenshot does not list the AR add on for the iOS viewer. Neither does it list my “Classic” Sketchup Pro 2020 license.
I am confused more then ever now…
