Can we use the same license key on production & development?

I entered the license key on production and everything worked, but our dev site is not accepting it. Can it not be on both sites simultaneously if they’re both off of the same domain?

That should not be a problem at all.

If the automatic updater in the dashboard doesn’t work for you, you can always update it manually.

You’ll find the Pro download in the same Account page as the license key.
