Live Traffic Stops Working

I like to fly with live real-time traffic. But sometimes the departure airport is too crowded. I used to be able to turn Traffic off for taxi and takeoff, then turn it back on again once my flight is underway. But for a few months now, when I turn it back on, live traffic will not work during the flight if it was turned off on the ground. I will only see multiplayer aircraft during the flight until I land, and then real world traffic reappears. Has anyone else noticed this? Is this a bug?
Thanks,

Joe

It’s really haphazard! Same with car and boat traffic.

This is happening to me as well, real time online is always on for me, I never change that. I have got live traffic during takeoff and landing but almost none during cruise. Started happening since SU7.

Edit: I now need to change air traffic quantity and quality to high or ultra to see live traffic during cruise (both were on medium). I thought they were also on medium before su7 but maybe they got reset somehow or I am remembering it wrong.
