Did you test the document with Microsoft Word or LibreOffice to see if they open the document ? This is a new feature correct in the professional version ?
SoftMaker‘s TextMaker can open the file without a problem.
Thanks for the information. I would suggest you inform Corel Support especially since they are promoting the fact it can do so.
What is the best way to reach them?
Log into your Corel account and you can find the technical support or see if this link works for you. https://www.corel.com/en/support/?storeKey=us
