transfer pictures from my R5 to I-Phone

How do I transfer pictures from my R5 to I-Phone.  It used to work with the app on my I-Phone, but recently it no longer works.  Please advise how to connect.

Welcome. 

I suggest that you try to reset the wireless settings in both the iPhone and the camera.  

Delete any and all saved configurations in the camera and the phone.  We may need to do a major “do-over” following a software phone OS update.  Apple seems to have just recently released a major update.
