It appears that once you write a description in the dashboard view of a Carto map (where it says "Add description...") the text is un-editable. Is there a way to edit the text?
You cannot edit an existing description or tags from your dashboard. You will need to open the map and change the metedata.
1-Open the map submenu and click on
DESCRIPTION and save it.
Editing your map info from the dashboard is a nice feature to have so I will pass your feedback to CARTO's Product Managers and designers (disclaimer: I work at CARTO).
