I have an mBrace account for my 2018 E400 that is supposed to provide me with live traffic data. Unfortunately, I often find that am not receiving live traffic data. This is especially irksome when sitting in traffic on an interstate highway. I have called mBrace support a number of times while in the car to report the issue, and while I may get live traffic data the next time I get in my car, the experience is short lived. Overall, access to live traffic has been very intermittent. Is my experience unique or have others had similar experiences. Is there a fix?
