If you can wait for a couple weeks. Wwise 2022.1.0 should be released sometime in November.
The beta preview builds are labeled "not for production" because:
- There are certain elements that are not stable, that could introduce delays in your production
- There are missing features
If you really wish to use the 22.1 features now, you could try the preview on a development branch, and update later. Otherwise, starting with 21.1 and migrating to 22.1 should also be fine.
