What I did:
I copied a Numbers spread sheet with the share option into an existing note. A few days later I updated the Numbers spread sheet and wanted to replace the outdated spread sheet in the note with the updated version.
After I selected the note in the share dialog of Numbers, the process aborted without copying the updated spread sheet into the note.
Copying the updated spread sheet to another or new note with the share option worked fine.
Renaming the spreadsheet did not help either.
What I expected:
That the repetitive sharing of a document with the same note is possible via the share option of the document.
Things that might be helpful to know (Agenda version, OS and model, etc):
The problem occurred with both the macOS and iPad versions of Agenda. macOS, iPadOS and Agenda are the latest versions.
