Hello see the attached screenshot. ETAs are before the actual time ! Saw this isuue on several flights. Looks like a random issue and after manipulating the MCDU the estimates are recalculated with no error.

known bug atm. Word is this is being fixed for the next update...

 

Edit : When the bug is present, if I go to the TIME page, and switch the ACFT TIME REF to MANUAL then back to AUTO, the ETA calculations come back to normal

It is enough to keep the TIME page constantly open on one FMS. But of course you lose the flexibility of having 2 FMS, so hopefully this will be fixed in the next update.

I agree. I also noticed that the "trick" I mentioned doesn't work every time, or you need to manipulate the page several times. Also, sometimes the ETA calculations remain accurate throughout the whole flight. Looks like a random bug.
