Hi, I have an issue with saving a copy of a file from the iPad version to be edited on the Mac version of Affinity Photo. From the iPad version I use "Save A Copy" and then click save; it does not seem to matter if I select "Save history". I then save it to a location on my iCloud Drive. When I try to open it on my Mac I have the following error message, "Failed to open document, The file includes features from a later versions of Affinity. (See Attachment) Does anyone have any suggestions on what I might try? My iPad is a: iPad Pro 10.5-inch 2017 OS - iOS 11 Running Affinity Photo version 1.6.4 My Mac is a: MacBook Pro Retina, 15-inch, Early 2013 2.4GHz Intel Core i7 w/8GB Ram OS - 10.12.6 Running Affinity Photo version 1.5.2 Thank you!
