Photos changed on web site not changed on app

I updated the photos for my listing on the web site but they are unchanged on the app. Actually, a few photos that I deleted on the site and replaced with new ones just show a blank on the app. If I delete the app from my phone and reinstall, will the updated photos appear? Is there a delay and the photos will repopulate later? I want to put up some new dates soon but not before the site and app listings match.

It seems it just takes a while for the app to register the updates.

try logging out and logging back in or refreshing the app it might be an older and the app is not refreshing
