Oceanic (OCE) and South American (SA) servers do exist and are up and running in THE FINALS.
Currently, we have a UI error that causes them not to show up as selectable in the settings menu. However, if folks in these regions keep their server location as the default auto-select, they will play on their local servers.
It’s truly a shame that we had these issues, but very soon we will have a fix for this, and OCE and SA players will be able to see their server location on the list.
In the meantime, OCE and SA players are playing in OCE and SA servers.
