Hey there,
First off all, it seems to have been resolved in the next release. Great going with multiple releases per week!
If it's still out there for others: I see a post, click the image (either main posted image or some image in the comments), then I click the dots menu at the bottom, image info comes up. I click the downward facing arrow and then the app freezes, some 5 seconds later it gets closed (presumably by the OS?). Happens (happened) every time.
Wither way, fixed in the last release I received this morning
