My usual workflow is to start a new screen session each day using a custom screen startup script (since I have some env vars I’d like to renew each day).
I had to then ssh into a remote machine and run a daemonized job in screen that wrote some output I needed to revisit.
The problem arose in that when I tried to detach from the inner screen, I ended detaching from the original screen I had started on my local machine. After some quick googling, I found this.

Can also do:
$ screen -d -D
