I discovered that the plugin Popup has some problems with upload field on IOS.
It’s the popup plugin and its connection to conditional logic.
When I create fields for upload image with pop up on, the fields don’t work.
But when I create upload field with conditional logic and if I select the option and activate the field with conditional logic, it works.
Without conditional logic the field doesn’t work.
If I disable popup plugin the upload fields works. If I enable prom popup form it doesn’t work.
If I make that upload field activated with conditional logic, the upload field works.
