I got my EQE 300 like 2 months ago, and from the get-go, the app was being a pain. After the first update, it just froze for a solid week, no progress. So, I called the Mercedes Me helpline, and they did a reset, which worked... for like, a hot minute. A few days later, the same issue hit me again. They told me to swing by the dealer for an MBUX software update - one that couldn’t be done OTA. Took it in last week, and now, every time I peek at the app, it actually updates the car’s location and charge status in real time. Finally, it's working like it should! Thank goodness!
