Hello Bhumika,
Thank you for your response! Yes the search result thumb view shows correct photo in correct photo on the desktop or mobile browser. It only has this problem for mobile apps (I have an iPhone, but suspect android may have similar issues if they employ the same caching strategy). One can reproduce the bug using the following steps:
1) Search for a destination where you property resides
2) View your property in the search result thumbnail (or Carousel), flipping through all 30 photos
3) Update photos in your property listing (e.g add a few more of replacing existing ones)
4) Perform the same search, saw old photos show up in the thumbnail/carousel. Notice the same search shows correct results on desktop and mobile browsers
