Unable to share contacts via Messages
Hi --
I am unable to share Contacts via the Messages app anymore. The "Message Card" option for content sharing from within the Contacts isn't working--nothing happens when I select it. Sharing by Mail works fine, and the Messages app otherwise seems to be working (sending and receiving messages works fine), so I think the issue is related to Messages receiving and responding to the request to share from the Contacts app.
I've also verified that I cannot share my 1Password entries via Messages either.
Is there a way to debug this, or reset the app-to-app connectivity on the Messages side?
Thanks
