This app is so limited. I can plug in to my charging station at home, it will charge. I can later tell the system to stop charging to avoid paying peak hour rates. But I CANNOT tell the car to continue charging even though it recognizes the vehicle is plugged in. There is no charging history. This app is a good at letting you start the car and climate control. But for charging purposes it's about as basic as it gets.

It's extremely slow to communicate with my Lyriq, like unbearably slow. I really wish I had a third party option, because I'd ditch this POS in a heartbeat. It's so bad that's it's not even just an annoyance, it's actually painful to use. I hate it. I hate that I can't just easily change my target charge cap without wondering if the update actually went through or without having to restart my phone because it's quit responding. I have a Galaxy S25 Ultra and always great connection.

Update 6/17/25, this update is much better, just have to touch command buttom and it sends the command, nice job developers! This update isn't much better than the previous updates. Now, it takes me at least 3 times to hold the command button to finally send the selected command. As with the last major update, having to hold the button till command is sent is a pain and when you're walking, is damn near impossible, very temperamental. There has to be a better platform.
