Since a long time ago, people cannot join me if I am not in their friends list. There's no error code, just "Unable to join". I do have Destiny 2 on Steam. I have followed all the steps in the following guide: [url]https://help.bungie.net/hc/en-us/articles/360049496751-Advanced-Troubleshooting-UPnP-Port-Forwarding-and-NAT-Types[/url]. Despite this, people are still unable to join me, even though my squad settings are adequate. I'm not really sure where to look anymore to solve my issue. Thank you in advance for your help.
