When I bring up an image by itself, I can do a long press on the image and get the app Safari drop-down interface (see attached), which gives me (along with other tools) the option to download the image to my camera roll or to copy the image for pasting elsewhere.

Unfortunately, the Avelon app blocks this action entirely.

If there is a workaround, it gives no indication as to what it is, forcing the user to thrash around and discover the box with the out/up arrow in the lower right.

If there is a way to whitelist this behaviour, there is also no way to inform the user on what setting they need to adjust.

At any rate, this is a noticeably frustrating suboptimal UI/UX, and should be addressed.
