File Upload fields do not work in Safari on iOS

When testing the form, the File Upload fields are greyed out and do not work on my iPhone or iPad.

This issue is not generated by RSForm! Pro, but by the Mobile version of Safari which does not allow users to upload files in the File Upload fields.

Being a restriction from the browser and the operating system, there is nothing that can be done from RSForm! Pro regarding this, as this will have to be adjusted from iOS itself.
