FlyXC does not load IGC/KML from URL

Hello,

I'm using FlyXC to show track and task by openning a link with references to IGC and KML files.
It was OK for a long time, but now I see just map.

This is how I open it:

https://flyxc.app/?track=http://crc.team/netcat_files/1553/1553/2025.09.02_YP2_821.igc_syncstart.igc&track=http://crc.team/netcat_files/1552/1552/T761_Slvn_15m.kml

Is this way still supported?
