Why can’t I join people who invite me?

HI there Noagral2004.

I am Lumie and I would love to assist you today.

I am so sorry you are having issues with opening your social notifications.

Here are some ideas:

System and Network Issues
System Software and Updates
Ensure your Xbox Series S has the latest system update. Sometimes, missing updates can cause compatibility issues with multiplayer functions.
Go to Settings > System > Updates & downloads and select Update console if an update is available.

Network Connectivity
Check if your network is stable. An unstable connection can prevent your Xbox from properly communicating with servers.
Go to Settings > General > Network settings and select Test network connection to diagnose and fix issues.

Account and Privacy Settings

Privacy and Online Safety
Sometimes, restrictive privacy settings can prevent you from joining games or accepting invites.
Go to Settings > Account > Privacy & online safety, then select Xbox privacy. Choose the appropriate settings to allow multiplayer and accepting invites.
Account Restrictions
If you’re using a child account, there might be restrictions set by a parent account.
The parent account needs to adjust these settings through the Microsoft Family Safety app or the Xbox Family Settings on the console.

Invitation and Notification Issues
Notifications Settings
Your notifications settings might be preventing you from seeing or responding to invites.
Go to Settings > Preferences > Notifications. Make sure the settings for game and invite notifications are enabled.

Invitation Expiry
Invitations can expire if not responded to promptly. Ensure you’re trying to join as soon as you receive the invite.

Software and Cache Issues

Clear Cache
Clearing the cache can resolve issues caused by temporary files.
Turn off your Xbox completely by holding the power button for 10 seconds. Unplug it for a minute, then plug it back in and restart.

Reinstall Games
Sometimes, the problem may lie with a specific game. Uninstalling and reinstalling the game might resolve this issue.
Go to My games & apps, select the game, press the Menu button, choose Manage game & add-ons, and select Uninstall all. Then reinstall the game from the Microsoft Store.

NAT Type and Port Forwarding

NAT Type
The NAT type affects your ability to connect to other players.
Go to Settings > General > Network settings and see if your NAT type is Open, Moderate, or Strict. Ideally, it should be Open.

Port Forwarding

Forwarding specific ports on your router can help improve connectivity.
Forward the following ports on your router:
Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)

Xbox Live and Account Issues
Xbox Live Status
Sometimes Xbox Live services are down or undergoing maintenance, preventing multiplayer connections.
Visit the Xbox Live Status page to check for any outages.

I hope this helps.

I shall be here for your response. -Lumie

This is why I suggest you be careful on who you join parties with. Always watch who you trust. If it is random people dont join the party invite.

I can’t even invite/join my friends’ parties because I can’t get to the commands that let me do so.

I have the same problem! I can join other people’s worlds, but when i create a world people can’t join my world even when I invite them. I have cellular data does that have anything to do with it? When i go into settings in Minecraft it wont let me turn
on friends of friends. Please Help! It is ios.

Mine is the exact same. I can’t invite or join anyone either.
