Invalid FPLAN Uplink

Hi all. Getting the Invalid FPLAN Uplink issue for the FENIX A320-CFM from KSEA to CYYC using Simbrief. Definitely selected correct aircraft, even paid for the Navigraph subscription and installed updates which shows in the MCDU as being up to date. Not sure what I am doing wrong? Flight plan below:

KSEA/34R N0439F350 MONTN2 SEA DCT ALPSE DCT YDC DCT MENBO DCT NORET IGVEP7 CYYC/35R

Really hoping someone can help as this was one of my favourite routes that I can no longer do for some reason. I’ve even reinstalled the entire simulator. Any help greatly appreciated.

Hi, the route looks valid.

I’m afraid you’ll need to reach out to Fenix for them to investigate why the import is failing.

Best regards,
