DroneLink Mobile for Android - Beta v4.0.0 (2211) & Mission Planner v2 for PC on Firefox

Sorry not to have posted sooner, but our house and its heating system has been undergoing major remodeling since the end of May (going from oil to propane-fired hot water boiler system), and today is the first chance I've had to return my attention to the Mavic Air 2  and updating all of the firmware (airframe 01.01.0920; RC 04.11.0034; Fly Safe Db 00.01.27) and DJI Fly app (v1.6.9), and to restart testing the new DL panorama feature, and eventually, its mapping mission feature as well.

After uninstalling DronelinkLink Mobile for Android v3.4.1 (2208) | Kernel 3.4.1, I installed Beta Version 4.0.0 (2211) | Kernel 4.0.0 on my Samsung Galaxy 5G SM716U running Android 12 without issue.

Turning to the previous bookmarked URL for the beta dashboard: https://app.dronelink.com/vkbellis/mission-planner-2-0-beta, I'm instantly redirected to the old dashboard for DroneLink PC on Firefox; i.e., DroneLink v3.4.1 | Kernel 3.4.0. Efforts to follow other links results in "You're not authorized to access this page", or from another link resulted in "Site Not Found".

What is the correct URL for Mission Planner v2 on Firefox?
