This week I had maddening issue with "The form contains unsupported data" with layers. I went into Field Maps Designer and the fields were highlighted in purple with same message. I hit the trash can hoping to just remove the field and then add again to resolve issue. It then prompted me if "I was sure I wanted to delete field" which I said yes thinking it was just the form. Then I noticed that those fields and data are now missing from database. IS IT POSSIBLE TO DELETE DATA FROM FIELD MAPS DESIGNER?!!!! Or were those fields somehow deleted prior which caused the error in the form. No idea how the data was deleted otherwise.
