**MSFS 2020 SimBrief Dispatch authentication completes successfully in browser/QR/code, but MSFS never changes to logged in. Community folder isolated, plugin reinstalled, tokens revoked, caches cleared. QR, manual code and link all produce the same result.**

Hi;…,

Welcome.

You might have a comms problem. Try disabling your Antivirus and firewall, resetting your modem, and connecting to the internet via a mobile hotspot.

Also, try logging into [https://dispatch.simbrief.com/](https://dispatch.simbrief.com/), then accessing SimBrief Dispatch in MSFS 2020.

Cheers

Ian
