I'm having the same issue as above. Just started on my iphone 6, running iOS 11.1.1.

I needed to perform a factory reset on my phone, downloaded Sub Rosa, etc. When I insert the card reader I get the white active light, but no blue 'read' light as before. Also, the screen shows a "no" symbol in the upper left; the red circle with the strike through it.

The same card and reader works fine on my iPad, but does not work on my iPhone; both are running Sub Rosa 4.0.2 (8835). My iPad is still running iOS 11.0.3.

Hopefully it's not a new iOS issue. Any help you could provide would be appreciated.

Thank you.

You may want to try cleaning the lightning port on your iPhone. There could be some obstruction that is preventing a solid connection between the reader and the phone.

Can you tell me if you are getting the status icon in the upper left of the Sub Rosa browser window when you connect the reader and/or insert your card?
