How to use the Hoppie CPDLC?

Hello,

I wanted to use the Hoppie CPDLC capavilities in the A350 but I can't find how to make it works.

1) I created a hoppie account and got my logon code.

2) On the hoopie web site, I switched my acccount to use IVAO.

3) In the A350 options, I entered my hoppie logon

4) I turn on the power on the A350, import my simbrief flightplan, turn on the IRS and wait for the IRS to be aligned

5) I then go to ATC.Com page on the A350, select IVAO and as I see on some youtube videos, I should be able to see all the active stations accepting CPDLC in the drop down menu but the list stays blank.

6) I try to go to the D-ATIS page, request ATIS for my departure and destination airport but I never received any answer.

So either it is not working or either a missed a step here but I'm lost. Can someone point me in the right direction please?

I try to switch my hoopie account to VATSIM and try on VATSIM but same.. doesn't work.
