I also saw multiple people report a coolant valve fault after the latest update. Coincidence? Well, as it turns out, yes.Just read the thread to see how people getting the same problems AFTER the latest update . Coincidence? NOPE !
Regardless, I understand the frustration and I wish you the best of luck getting the issue fixed ASAP, but responding negatively to random posts here just because you're frustrated with something else entirely is not going to help anyone.
