Clamshell mode with MacOS Catalina
Unable to use Clamshell mode (laptop lid closed) with MacOS Catalina. I always get the third display, despite my laptop being closed.

Piggybacking, though my issue is slightly different. I updated to Catalina 10.15.6 and had to download the updated DisplayLink Manager. Since the update, if I close the MacBook, every 5 minutes or so the mac appears to go to sleep and wake back up and prompt me for my password again. Unusable. My workaround is to ALMOST close my MacBook. We'll see how that works out.
I am having this same issue.
