Two machine installation of software...

Hi,

I have two Macs, a Mac Pro laptop and Mac Pro desktop, both are running the latest version of OS Sierra.

I've owned Affinity Photo for, I think, nearly a year. Photo is installed on both machines. Depending on wether I am on the road or in my studio, I share the project documents through Dropbox.

I don't remember which machine I purchased Photo on through the App Store but when I went to the App Store on the other machine I was able to install it there as well.

I just purchased Designer on one machine and want to install it on the other, but when I go to the App Store on the other machine it seems to want me to purchase it again.

How do install on both machines?

Please help.

Thanks!

I didn't find the right solution from the Internet.
