How to import a match definition file ***.psc on iOS devices?

@Andreas_Pfenninger
You are asking about PS 1.0? You know we have long moved onto the new PractiScore 2 app and are not supporting 1.x apps anymore.

Part of the reason is that in 1.0 they were two completely different apps and did not have the same functionality.
If you must import a match file to 1.0 you would email it in and then open the email. When you download the file you will be able to download it directly to PS in the email. That is only an old iOS function.
Please move over to the new App.

But, if you must.
