People looking to hop into friendly Apex Legends squads today may run into a pretty significant issue: Origin is acting up, and it’s causing people to show up as permanently offline.

The error seems tied directly to Origin, as players are able to launch and play matches of Apex Legends, they just can’t join friends’ games, since they’re listed as being offline.
