The Miro integration was announced almost a year ago and works great - for one way integrations: https://community.airtable.com/t5/announcements/new-feature-announcing-airtable-s-miro-integration/ba-p/128357
However, I would really need a two way sync, or at the very least a smart hack to achieve something similar.
The best solution would obviously be a two way sync of the Content field. (This being the primary field I guess it could cause issues.)
The second best option (pending better ideas) would be to have a second Content field.
One possible ugly hack (for my use case) would be to use a huge number of Frames (acting as IDs) and have the Content field editable from Miro. This could work but since I need 180+ Frames for the current case I don't really think it is feasible.
Think of building an org chart in Miro (where names can change) and still wishing to link these to more data in Airtable.
