Freeform corrupting files on all devices except original

I have been trying to use Freeform on my iPad Pro M1 (fully updated iPadOS 16.3.1) to take handwritten notes using my Apple Pencil.

When I try to open those documents on Freeform on my Mac (macOS 13.2.1) or my iPhone (iOS 16.3.1), the documents appear to be severely corrupted.

Some of the text is readable and matches the original, but most of it is very disjointed and missing/moved/unrecognizable.

When I go to the iPad, the original is still perfect.

If I duplicate the original from the iPad, the new files (as long as I don't edit that duplicate) appear to be perfect, but if I reopen it on iPad and try to edit it again, the files start getting wonky.

What is going on here? How do I get these files to be usable across devices? I'm probably going to have to switch back to Miro at this point, since it's making my learning hard (and Thai is hard enough to learn as it 🙃), but I would love to use Freeform instead if we can get it working!

Thanks so much,

Adam
