Myths and facts about how file authorization works (authorizing file A to access file B as described at https://help.claris.com/en/pro-help/content/authorizing-access.html). It keeps causing headaches to developers (including my team as you can see in https://community.claris.com/en/s/question/0D53w00006DNof8CAD/issue-with-requesting-aut[…]n-for-already-authorized-file-while-accessing-another-file and https://community.claris.com/en/s/question/0D5Vy000005PR2fKAG/protected-file-multiple-instances-authorization-issue). Let me share my discoveries when FileMaker switches from "Hey friend, feel free to grab my data." to "I don't know you, I don't trust you, dude!". We may also come up with a mutually agreed proposal for Claris how to improve this important security feature for the future.
