Update:I don't know why or what changed I can see it now!
Hello, and thank you for your report. To unlock patrols, you can either play through Forsaken's campaign some, or do the level cap option. It's not leveling up once past the base game, it's leveling up once past your level cap. So if you do own Forsaken, that would mean reaching level 50 and then leveling up again once.
