RE: Business card scanner in D365 retain card image issue
Hello,
thank you for your reply Wahaj, that is part of the solution, but it's not all, because I already have that setting.

I did, however, manage to figure out the behavior, which I can consistently reproduce.
I must
a.) use the side-record-selector and select the record for a 2nd time, or
b.) Refresh on ribbon
Accessing the record in any other way never shows the Business Card (from regular view, from Advanced Find, via direct link, pop-out-window, browser refresh/F5, Ctrl+F5).
Additionally, F5 or Ctrl+F5 actually hide the Business Card it if it was previously shown using a.) or b.)
The behavior is consistent in Chrome, IE, mobile app (Android) and mobile Chrome.
(So, I discovered that my business cards were actually being saved within the system.)

I am running online deployment:
Microsoft Dynamics 365
2020 release wave 1 enabled
Server version: 9.1.0000.19857
Client version: 1.4.1024-2006.4
Maybe the development team catches on to this and fixes the behavior to simply display the Business Card.
I hope this helps someone.
