I tested a round-trip scenario with Polarion:
1. Exported reqifz document from Polarion
2. Edited reqifz in ReqIF studio: Added new images to the requirement description
3. Imported document back in Polarion.
However the images will not be displayed, instead following text appears in the document: Missing embedded object: ReqIFExchange/Equation%20editor.PNG
What am I doing wrong?
