Hello,
Thanks for contacting us. Do not worry. The functionality of the product description is not changed.
Some files of WC were rewritten in our theme http://prntscr.com/po3w6x , but we have been able to achieve the desired functionality via filter https://developer.wordpress.org/reference/functions/add_filter/ so the mentioned files were deleted from the XStore. These files are loaded from WC plugin automatically now.
You should not face any problem after the theme update, but it is recommended to do a backup – https://xstore.helpscoutdocs.com/article/63-theme-update
