Hi emmrecs01,
Thanks for your reply.
Yes, I have found another thread which suggests this as the solution so I tried that, I have tried opening Publisher first, then opening Photo, and opening Photo First and then opening Publisher, both to no avail. I have even rebooted my MacBook to see whether it needed to be done, same result. I have checked the location of my Affinity Apps and they are all in the Applications folder on my computer as this was also suggested as a potential problem. All are running v1.8.3 and Designer is already linked so I know the versions are compatible. Confused
