Hello, My brother and I both have Star Trek Bridge Crew purchased through the Oculus Store. A while back I purchased the TNG Update as well (through the Oculus Store). No problems.
Recently, my brother tried to also buy the TNG Update but it didn't show up in the Oculus Store as a stand-alone item to purchase. In the end, he bought it through UPlay. It installed. But he can't access the TNG content in the game. I have to disable TNG content for us to play together.
