For a week or so now, tapping on photos in the eBay app doesn’t bring up the photo up. Happening across many items. 
Example. 
search for vases, brings up list. 
tap on item of interest. 
Horizontal photo scroll and listing details appear. Tap on photo. 
All photos then appear in a vertical scroll, except the initial tapped photo (see attached photo) Appears as a blank space in the scroll.
Can happen if tapped photo is from any place in the horizontal scroll. Eg vertical roll can appear as photo, photo, blank, photo. 
tapping on a photo from the vertical roll brings up another horizontal roll and the missing photo is now there.
