Hi, please find the relevant information on the bug below:
Affinity Photo version is 1.8.3.180, and iPad Pro (10.5-inch) is on iOS 13.3.1;
I cannot reproduce it, but it happened twice already. One time occurred when I was working inside a project folder, rearranging documents, and all of a sudden, another project appeared inside; another time occurred when I was rearranging the orders of the project folders, one project folder went inside another. There is no way I could get that project out because the only option available was "Rename".
I think if you could allow a project created inside/moved out of another, this bug could become a feature
