I am using SignaturePad in a PCL project. Pad works great on Android, no issues. I can use the Pad on iOS simulator - 6s 9.3. I can't verify image capture as I have GPS location requirements coded in app which is not supported in simulator - at least MacInClouds. When I deploy it to App store/test flight and run on my personal phone the signature pad displays. The signature "X", line and clear don't show up. The pad doesn't even respond to my signing with my finger. Is there a "touch/gesture" permission that is required?
