Android not capturing photo from within Monzo

I tried to attach a photo to an item - by taking the photo within Monzo.
Takes photo OK, and I accept it - but then the photo does not appear in the Monzo transaction; and there is nothing added to the phone gallary as far as I can tell.

It’s OK - if I take the photos “outside” of Monzo, then attach them. (Except the rotation issue - see other thread).

Samsung Galaxy S3, Lollipop on O2.
