Hi Billy. The “Restore Document from Export” needs a file that would look like this:
which would be inside your .hypresources folder as well as the .hyperesources content.
Do you have this file? I suspect not if your document came from 248 (v2.0.2) as you have stated that the option isn’t available in 248.
What’s your reason for restoring from this document. Perhaps there is another way we can achieve what you want to do
