What I did: Continued using the Copy As, HTML function after upgrading to Agenda 13.0 (187).
What happened: When I paste into another program (Outlook, Word, Pages), it now appears identical to Markdown. Only the Note Text (RTF) preserves formatting now.
What I expected: Formatted text, as would be the case when I used this function prior to this Agenda upgrade.
Things that might be helpful to know (Agenda version, OS and model, etc):
macOS 11.1, Agenda 13.0 (187)
