The app successfully pairs with my charger via Bluetooth, but that’s where the utility ends. I can set the breaker type, but I am completely unable to configure Wi-Fi or access any advanced features. I’ve searched forums and boards for solutions only to find many others stuck with the same issue and no fix in sight. It is incredibly frustrating to have high-end hardware held back by such non-functional software. Extremely disappointing. UPDATE: 2 months later and haven't heard a word from GM.

Worthless App. It shows under myCadillac app. Crazy thing is my Escalade is gas powered. I also have a 2025 Hummer, but doesn't show under it. The moment I downloaded this Ultium PowerUP app, it's telling me it won't connect to Bluetooth anymore. I have the hardwired PowerUp plus charger, which is now my second one. The first one was a dud and turned red all the time. Now I can't get in and change any settings on this charger. Don't understand why this app is causing a mess with my charger.

Does what it says but would be nice to have additional features like connecting to the internet and is equipped with advanced features like Create schedules to take advantage of lower utility rates, restrict access, see your usage history, and get real-time charging notifications. I can't seem to get connected to the charger via wifi.
