v2019 Windows 10 build 1809 or newer 1809 or 1903.  Customer, vendor, item maintenance,  Create a memo and add an Excel .xlsx attachment.  Save the memo then open the memo and double click on the attachment.  It won't open.  I brought this issue to Sage's attention in January and was assured it would be fixed in version 2019.  I don't even see a KB on the issue now. Can anyone else replicate this and if so does anyone have a solution other than saving files as .xls?  The customer is throwing a fit because they use a lot of complicated formulas in the attachments and apparently need the .xlsx format for attachments.
