twilight drop off Edinburgh

[ruby77]

Hi I have a parking space booked at edinburgh airport for the duration of my holiday. I am allowed to use the 1 hour car park within the terminal parking area for free whilst I do the twilight drop off. I have used street view to try and work out where this is and the signange disappears! I don’t want to make a v costly mistake and use the wrong car park. Have any of you used it and can help?
I am going to try and attach a photo of where i think it is but can’t work out which barrier to go through. Thanks

I should add that I have contacted the airport but haven’t heard back yet.

If you're talking about the normal drop off point then it's clearly signposted at the airport. You won't miss it

For terminal parking go along the road into the Airport, straight on at the first roundabout by the Hilton and Moxy hotel and at the next roundabout (almost immediately after) go straight on again rather than round the one-way system towards the terminal building. Then it's the barriers to the left following the red arrow on your photo. It's not the drop-off point, that's for set down of passengers only, you can't leave your vehicle.
