Bit silly perhaps but read on, it may help others (me: Win11, MS2024, RTX5080, I9)
Simlink asks to login to Navigraph, and then it hangs for ages. Re-install does not help, other people also struggled with this, like me. I had this yesterday again, no idea why.
The solution? I use Firefox, in the top left corner Firefox wants to open a new page and asked my permission. I never noticed this because this happens only occasionally in Firefox. Press ‘allow’, fill in the page: problem solved! Silly, I warned you, but it solves the problem for me. I hope for others too! best regards, Ben
Thanks for letting us know
