Unable to sign in from MSFS 2024 to Simbrief Dispatch

Hello There,

I’m a free Simbrief user… I have the same issue as some have posted - from inside 2024 clicking on “sign in” does nothing. Cannot use Simbrief from inside the Sim? Same for a buddy of mine who has tried it. Worked fine in 2020.

Any workaround for this please? I’m not a Navigraph subscriber so I can’t use the Navigraph Hub.
Thanks
