Save Photo ios Perspective App

Hi, is there any way to save a photo or save files using the ios perspective app?

When I tested saving a photo on a page by long pressing the photo and selecting “save to photos” the app quit and did not save the photo.

I wasn’t able to test this yet, but one one page I have a button that will get several photos from a database and downloads them all with function. I was told the pictures open but then they are unable to exit from viewing the photo and have to reboot the ipad.
