Real Time not working but audience is correct
For the past 2 weeks, the Real Time function is not working anymore in my GA Account.
It was working fine since then.
The tag has not been modified in any way, and no change in the admin/configuration was made.
The strange thing is that the audience is still correct (I can have it the day after)
Only the Real Time function is showing 0 (sometimes 1 or 2 users active) whereas my active users should be around 250 users at the same time.
My site is using the old tag (ga.js) and gets around 650 000 sessions / month (25k / day)
Is it possible that there are too much hits/day so that the Real Time can not handdle them ?
I have other sites with much more trafic and still the ga.js tag and they still have the Real Time functions..
I really don't understand this new behaviour.
Thank you for your time and consideration.
