Acrobat Pro 2020 asking for sign in (Classic Track/Serial version)

I'm currently struggling with this problem in our VDI environment and I'm hoping someone can help.

We purchase TLP licenses for Acrobat Pro products - our recent purchase of some Pro 2020 licenses is giving me issues.

We use VDI for some of our users (both persistent and non-persistent) and use VMware appstacks to deploy applications to those machines.

The latest purchase of Acrobat Pro 2020 licenses are prompting users to sign in each time they launch the software.

I had this problem for Acrobat Pro 2017, but resolved it by using the adobe_prtk.exe to make an xml file with the serial number and run with the arguments --tool=VolumeSerialize --stream at log in.

I did the same for Acrobat Pro 2020, but it isn't supressing the sign in.

The string I used to create the xml for the 2020 Pro version:

--tool=VolumeSerialize --generate --serial=SERIALNUMBERHERE --leid=V7{}AcrobatESR-20-Win-GM --regsuppress=ss

This is the same string I used for the 2017, just with the correct LEID.

Before this, I also tried using the Acrobat Customization Wizard to edit the MSI and make a transform, but saw the same results.

My question: Does anyone else have experience with deploying Acrobat Pro TLP/non-Creative Cloud versions and successfully supressing the sign in prompt? Any best practices or other things to consider?

Thanks!
