Hello Gemlilies,
Thanks for posting in the Apple Support Communities.
Our understanding is that you're not seeing the Freeform documents you created on all of your devices. We'd like to help.
Follow the steps below for help with sharing across all your Apple devices.
"Start on your iPad, keep working on your Mac
The Freeform boards you store in iCloud—and any changes you make to them—stay up to date on all your Apple devices when you’re signed in with the same Apple ID. To use iCloud with Freeform, go to Settings
> [your name] > iCloud > Show All (below Apps Using iCloud), then turn on Freeform."
More information can be found in the two articles below.
