Errors While Filing Trip

I am running into an intermittent error when trying to file an IFR flight plan, though I am seeing the error more often now; after pressing the "FILE" button there is an immediate pop-up that reports "Errors While Filing Trip -- Timeout while waiting for request". This happens on various WiFi networks (all with good coverage/signal) and also over 5G mobile data. I am filing flight plans within Canada and have a valid subscription for Canada (Standard + Premium Upgrade) and the Subscriptions page within settings shows this as such and am filing IFR using the Leidos Filing Service.

My device particulars:

Garmin PIlot: version 24.8.0

Platform: Android 14 (stable, non-beta stream)

Device: Google Pixel 8
