Hi.  When creating a photo card, or inserting a photo into a text card, I am unable to choose photos from my phone's photo gallery.  I can select "gallery" from the options on the screen (at the bottom, next to "photo" and "document") and then go onto select a picture to include - however, after that, the app returns to the camera view, and ignores the photo that I selected.  This is on an iphone 6S, iOS 12.
