I’m using Xbox Series X + MSFS 2024 + iniBuilds A350. The problem occurs when starting the aircraft from a Cold & Dark state. I follow the normal startup procedure and import my SimBrief flight plan through the EFB. Flt Ops Sts and Load Sheet information both load normally. However, when I perform FPLN Request on the FMS, it remains stuck on “Pending Request” for about 20 seconds and then automatically returns to the previous screen. The flight plan is never loaded. I have repeatedly tried various troubleshooting methods, including re-importing the SimBrief flight plan, restarting the aircraft, reloading the flight, sending the FPLN Request again, switching through CAPT OIS/Center OIS and then importing again, as well as other related settings and procedures. I believe I have already tried pretty much all of the obvious troubleshooting steps. I have also seen other Xbox Series X players on YouTube using this function successfully, so I’m wondering whether this could be related to corrupted A350 data, cached data, saved aircraft data, or an Xbox-specific bug. If anyone knows how to completely reset the A350 data or fix the FPLN Request getting stuck on Pending, I would really appreciate your help.
