No, I’ve never heard of that. I think there’s something going on w/ your connection or when you’re starting tables in ignition. Keep in mind that it’s the most sensitive site simply because it doesn’t provide hand histories. I’d e-mail support from the drivehud app (top right) and let them take a look at your log so they can see what’s going on.
But yeah, to date I’ve not heard one person have an issue w/ sessions not recording.
