Middle click cut-paste not working after update (solved)

After a recent update, middle-click paste (primary selection) stopped working for me in GTK-based applications.

After some investigation, I found that the setting gtk-enable-primary-paste had been set to false.

gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true

Thank you! I use sway so had been digging through sway changes and docs assuming it was a change there. Above worked for me!
