Can't use deployed files on iOS

[Fivecord 0]

I'v made an iOS app where I want the user to select the style. In the deployment I have added some fsf-files which have a Remote Path set to StartUp\Documents

The style is set via the following code:

    astylefile := TPath.Combine(TPath.GetDocumentsPath, 'BlackRock_iOS.fsf');
    TStyleManager.SetStyleFromFile(astylefile);

Then I get the error: Cannot open file "/var/mobile/containers/Data/Application/.../Documents/BlackRock_iOS.fsf". No such file or directory.

If I inspect the file appname.app, the folder StartUp/Documents is present with the fsf-files in it, so the files are deployed.  

Thus something prevents my app to access the files?

 

I tried the same in a blank iOS app, where the styles are applied successful. 

 

Anybody an idea of what could be wrong?
