If Chats aren’t sending, loading, or won’t delete, there are a few troubleshooting steps you can try.
Update Snapchat
Make sure you and your friend are updated to the latest version of Snapchat.
Download the latest update for iOS or update for Android.
Check Your Internet Connection
Make sure you and your friend have a good internet connection. Try connecting to Wi-Fi or moving to a spot where you have better mobile service.
Close Snapchat and Reopen It
Close the Snapchat app and then open it again. This can help with Chat issues.
Free Up Storage Space on Your Device
You can clear your Snapchat cache to free up storage space on your device. Clearing your cache won’t delete any of your Memories, Snaps or Chats.
