I'm using a dashboard, including the Rich Text Widget to free form text. all worked fine yesterday; Today, each widget has separate 'text boxes' within the typing space, that make it very difficult to manage/update in a timely fashion..
I'm not able to reproduce what you're seeing with my own rich text widgets.
Did you copy and paste information from another site into your rich text widgets?
I know that rich text widgets will pertain some formatting if you copied information over from a website, word doc, google doc, or other source that has rich text.
This formatting could be causing the "text box" effect that you're seeing.
If that doesn't work, reach out to our Support team to troubleshoot further.
