Licencing - Local dev

Hi,

Does it matter if I install my licence key on my local development environment or my live site,

I’ll be pushing/ pulling git updates a lot so though it might be ideal to register on the local development environment, somehow, but that says it will be registered to my local dev env domain name. Which is different to my live domain name

localdev.blahblahblah.com rather than blahblahblah.com

You should register the license on your production domain, not on develop.
