Re: "When I share a screenshot to my freeform ipad app it doesn’t appear".
Wondering if Apple Support's online article (link below) can help:
Add photos, videos, stickers, scans, links, and other files to a Freeform board on iPad - Apple Support
Eg: says:
"You can add any photo or video to a Freeform board, or take a new one with your iPad camera. You can also add any kind of file to your board by
scanning,
linking, or
inserting it."
The aove article has the "how-to" info,
or also says:
"Tip: To add a photo, video, file, or link to a Freeform board from supported apps (such as Notes, Photos, Safari, and more), select it and tap
in the other app, tap the Freeform app icon, then tap New Board or the name of an existing board."
If the methods given in the article are not working for you ...
If not already using it: you could try updating your iPadOS to the newest version (Wise to back-up first)
(To check for updates: Settings > General > Software Updates)
or
You could try re-starting your iPad and try adding the screnshot again
You can always send feedback to Apple to help improve the app software:
