I have an instant flow that takes a text input and a file input.

This flow has worked fine and when I ran it my Android Phone(Pixel 5 running latest version of Android) asked me for the source of the file and offered me the camera and the option to choose a file from various storage locations.
All of a sudden the option to use the native camera as an input has gone and I can now only choose to add an already stored file.
Has anyone come across this issue? Any clue whats happened?
Thanks in advance
