Acrobat PDFMaker Office Com Add-ins tab issue / Word, Excel Tab absent

I am working to assist a user whose Adobe tab in Word and Excel disappeared after an update. 

Office Version: Microsoft 365 apps for enterprise, 16.0.17328.20550

Adobe Current version: 24.002.21005

With this version, the tab does not appear in Word or Excel

Comparison version: 17.008.30051

Tab is present

Desired tab: 

Attempted troubleshooting:
1) Repair Adobe

2) Reinstall Adobe
3) Checked compatibility
     Per this chart, word and Excel should be compatible:

4) File > Options > Add-ins > Go
     Re-enabled / disabled add-in. Makes no difference. The functions for the Adobe tab don't even list under 

     Word > File > Options > Customize Ribbon > Dropdown = All Commands
5) Checked registry options per article:
     https://helpx.adobe.com/acrobat/kb/pdfmaker-unavailable-office-2007-office.html?x-product=Helpx%2F1.0.0&x-product-location=Search%3AForums%3Alink%2F3.5.6
    Everything appeared correct. Also tried registration steps. 
6) Start Word as Admin
7) Re-mapping to DLL file within Adobe add in directory. 

Everything looks like it should be there, but the tab is absent.
