Data Guard Fast Start Failover and FAST SYNC

Hello there:

I see a lot of info about configuring FSFO. And some info on FAST SYNC. But not much about both together. Is this a viable? I have gotten this error a few times in a testing environment when a failover was triggered.

Is FSFO and FAST SYNC supported together and could it be the cause of this possible data loss between primary and standby?

Thanks!
