Ticks are not arriving for specific symbols in DEMO account but DO WORK IN LIVE ONE

Hey,

I'm using IC Markets as my broker.

When requesting Market Data Request in live account everything works great!!

but if I run the same code in demo account I doesn't.

the below symbols don't return any data or produced any error.

Symbol       Fix ID

NZDCHF     39

NZDCAD     30

EURNZD      26

NZDJPY       21
