A. Ensure that you are logged into your account properly. Sometimes, logging out and logging back in can refresh your account data. Go to the app settings, log out, and then log back in to see if your items reappear.
B. Check if there are any updates available for the app. Go to the Google Play Store, search for Acloset, and see if an update is available. Updating the app can fix bugs that may cause items to disappear.
