Thanks @hyder - I have signed the OCA when submitting the PR but it's currently saying "Under review". Was there anything else I needed to do on my side?

Ah cool. Nothing to do on your side then. It should come in over the next 24 hours and the "OCA Required" label will be lifted. We'll merge it asap.

Thanks for your contribution. Very much appreciated.
