can't use flakes even if nix.conf is updated

[cole-h]

Could you please provide some more info?

• What installer version did you use?
• What version of Nix are you running?
• What happens when you try to use something that requires the flakes feature? (Screenshots or terminal text output would be helpful.)
• What are the contents of /etc/nix/nix.conf and ~/.config/nix/nix.conf?
• Does it start working if you restart the Nix daemon (systemctl restart nix-daemon on Linux, launchctl bootout system org.nixos.nix-daemon && launchctl bootstrap system org.nixos.nix-daemon on macOS, I think)?

I was troubleshooting this with someone today, they were getting messages about setting experimental-features = nix-command flakes etc.

@cole-h's post was useful for me, because I looked at the ~/.config/nix/nix.conf and noticed that it set experimental-features, and that those overrode the ones in /ext/nix/nix.conf, so for me deleting ~/.config/nix/nix.conf did the trick.
