The Fairphone OS Android 9 bugtracker is public. A new beta has been made available today to those who have signed up for the beta program.
On a different note, I would strongly invite everyone who has been using Fairphone Open OS for the FP2 so far to consider either LineageOS 17.1 (Android 10) or /e/OS (Android 9) for the FP2. Both offer Android without Google as well.
