I can provide some general information that might help explain why you can't see your friend's Snapchat score.
Snapchat occasionally updates its features and settings, and this might result in changes to how certain information is displayed. Here are some possible reasons why you can't see your friend's Snapchat score:
Privacy Settings: Snapchat allows users to adjust their privacy settings to control who can see certain information, including their Snapchat score. If your friend has changed their privacy settings, they may have restricted visibility of their score to everyone or to only their friends.
Blocked or Removed: If your friend has blocked you or removed you from their friend list, you won't be able to see their Snapchat score. However, you mentioned that they are still your friend on Snapchat, so this might not be the case in your situation.
Glitch or Bug: Technical issues, glitches, or bugs can sometimes affect how features are displayed on Snapchat. If you can't see your friend's score, it's possible that there's a temporary issue with the app, and it may resolve itself in due time.
Temporary Score Reset: In some cases, Snapchat may temporarily reset a user's score due to suspected spammy behavior or other reasons. This reset can make it seem like you can't see your friend's score, but it should return once they start using the app regularly again.
Snapchat Updates: Snapchat frequently rolls out updates and changes to its platform. These updates can sometimes lead to modifications in how certain features, including scores, are shown.
In most cases, if your friend is still on your Snapchat friend list and you have not been blocked or removed, it's likely that your friend has adjusted their privacy settings or there might be a temporary glitch. If you are concerned about the situation or curious about the reason, it's best to reach out to your friend and have an open and honest conversation about it. They may provide insights into the changes or reassure you about the situation.
