When is Corel going to fix the compatibility bug with current Illustrator files?

For the past few months I have not been able to open .ai files created with the most recent version of Adobe Illustrator. I opened a ticket with tech support and they are COMPLETELY USELESS. It doesn't help that they don't speak and understand English. 

The files I can't open will open and close just fine with Illustrator. However, they just hang when I try to open in Coreldraw 2019. I have all the latest patches loaded and I have uninstalled and reinstalled Coreldraw. If I open these files with Illustrator and save them to a legacy format then Coreldraw will open the file. This shows that they are NOT compatible with ai files like they advertise. WHEN ARE YOU GOING TO FIX THIS BUG COREL???????
