I've been using HLT for several months and I've never had a reliable experience in getting OBD data via an Automatic Gen II dongle. I'll get a green status and I'll see that engine data is being recorded but on the next session, not data is being recording and if I look at the Status screen, I see this:

I'm about to buy a new OBD dongle but before I do I thought I'd check here: has anyone had the same experience and found a fix for it? I've had the problem on two different cars (albeit both Cayman 981s), different phones, different versions of HLT. My Automatic dongle is running the latest firmware version.
Thanks,
Fergus
