I find that it works seamlessly and is very intuitive. So far I’ve also found it very reliable. I think some people who are finding it unreliable or buggy it may have to do with the kind of phone that you’re using. A faster processor definitely helps. I use an iPhone 12 pro max and it launches very quickly and works very smoothly
The app is good when it works, unfortunately it rarely does. It connects to the unit but a couple of steps into trying to get something done it just freezes and needs to be restarted. Navigating straight through the unit with the very limited remote is the only option.
