is the quest update almost done with testing.
Viewing post in Attack On Titan VR: Fan Game comments
I would recommend trying it out for yourself by becoming a tester. This update changed so many things for the quest version that it will have many bugs and need more optimizations to run how it should. For instance, this version of the quest update now shares all features of the most recent PCVR test build. So it will most likely be a little while until the update is made public to get the game running well.
