Hi Lsrwtr84,
If you set a shutter speed on the camera that is within its normal sync speed range, high-speed sync is no longer active and you will not see the icon in the viewfinder. This is because high-speed sync is no longer necessary. This could very well explain why you are sometimes not seeing high-speed sync active anymore.
If this is a time sensitive-matter, additional support options are available at Contact Us.
