My Son and I both have licensed Affinity Photo and Designer on our respective MacBook Pros. My Son has just upgraded to Affinity Photo v1.8, but this appears to co-exist will the old version, rather than updating it, so there are now two different installations of Affinity Photo. Also when I try to start the new version 1.8, I receive a message that this program is already open. How is this resolved please as I don't want to have the same user experience when I upgrade?
Also the 'default' program when loading a photographic image is now Affinity Designer, rather than Affinity Photo. How do I change this default please?
