There could be several reasons. It might be that your friend's account has some restrictions, or the platform's rules are preventing it. Also, it could be a connectivity issue on their end.
Maybe there's a technical glitch or a problem with the platform's settings. It could be that your friend doesn't have the right permissions or there's a bug preventing the repost.
It could be that your story has some privacy settings preventing reposts. Or your friend's account might have some technical issues. Have them try reinstalling the app or checking their internet connection.
The problem could be related to technical issues. Your friend's device might not be compatible with the reposting feature. Or there could be a problem with the network connection. Ensure that both of you have a stable internet connection. Also, make sure that the app is updated to the latest version on both devices. If the issue persists, contact the platform's support team.
If it's not a privacy setting issue, then both you and your friend should check if your apps are updated. Out - of - date apps can sometimes cause problems with features like reposting. Also, make sure your friend's account is in good standing and not restricted in any way. If all else fails, reach out to the platform's customer support for help.
There could be a few reasons. Maybe your friend has chosen specific settings that don't allow reposting. Or, it could be a glitch in the system. Try reaching out to the platform's support for help.
