We updated our system and all of the previously supported cars are there, with the addition of so many more. There are now cars on here that we have never heard of, let alone work on and it has made our diag system work like poop. Very sluggish and won't connect to a lot of vehicles it previously would diag.
What kind of new cars you can see now? As we mentioned before, new version will only add more cars and functions without any previously supported functions removed. Could you please re-install everything and check the result again?
