This shouldn't be a problem for Steam users, since steam updates automatically, but if you are not on v2020.9.9, you will not be able to play Among Us online soon.

If you are currently in a room, it will still work, but you will not be able to join or create any new rooms. You must update to v2020.9.9.

If you get incorrect version errors, please make sure you are on version 2020.9.9 (visible in the upper left on the main menu)
