Does Target Display Mode still work with Catalina?

I have a 2011 iMac that I used to be able to use as a Target Display for my 2017 MacBook Air. The iMac is on High Sierra and the MacBook is now on Catalina.

Target Display Mode is no longer working. Is this due to Catalina?

The article here:

Use your iMac as a display with Target Display Mode

is unclearly worded. It says 'Target Display mode does not work with Catalina', but which computer are they referring to, the display one or the displayed one?

The iMac (the Target of the MacBook Air) needs to be on High Sierra/10.13.xx or prior/earlier. I doubt this will resolve your issue, so you may want to try restarting both computer, resetting PRAM, changing cables, ports etc.
