Cannot sign out of Acrobat Pro DC; keeps auto signing in when I restart the app

Hi,

I have downloaded a trial version of Adobe Acrobat Pro DC app to my Windows 10 machine using my personal email account at Adobe. Then I cancelled my trial it and requested the Pro DC from my company. The request got granted, I got the link for the install. The wrinkle is that they automatically assigned my work email (which is different from my personal email) as my Adobe ID. 

Since I had the app installed, i tried following the link https://helpx.adobe.com/acrobat/kb/update-acrobat-manually.html, by going to Help --> sign out. The app signs me out and quits; however, as I restart the app, it shows sign-in screen for a split moment and then automatically signs me back in using my personal email address , so I see "Subscription Expired" in the bottom left corner of the app.

I tried unistalling Acrobat Pro DC, uninstalling Creative Cloud, restarting the machine, and re-installing the Acrobat Pro DC. However, it automatically signs me back in using my pesonal email. I can see my subcription in the web browser if I sign in to adobe.com using my corporate email. Any ideas? I have the latest vesion of the Adobe Acrobat Pro DC, 2021.007.20099

Thank you,

Sergiy
