Sorry, I just retested it again and it does not work. Indeed you have changed something, as the behavior is slightly different now:
When pressing on the camera icon, you see that its background is changing from black to grey.
But the problem remains, as the action when pressing the "camera" icon is to change to the next page, instead of displaying the metadata (even on short texts that don't place the camera icon on the side of the display).
Thanks, I don't know how this could happened - probably I forgot to finish it...
Now I (hopefully) fixed this. I have changed a lot of code (not for this bug, but to make it updated with the changes I made since in Story skin) - so I suggest to give it some testing before uploading. In my test everything worked, but naturally I can't test every scenario.
