As the title says, the feature has been going off and on for a while now. I usually haven’t been able to see who’s in a party, but it will work randomly. I don’t use a VPN, nor have I changed anything from when it worked. Also, the app says it’s up to date, so I don’t know why it’s bugged out suddenly these past few weeks.
Thank you for attaching your logs. I checked them but I do not see any recent issues with the party detection (your app logs are limited to the last 3 days).
For example, I can see that the app detected a party in your last match:
Did you see this party in the app during the match?
Also, please note that the party detection is based on the last 25 matches. If two players play in the same party for the first time, we will not be able to detect them as playing in the same party.
