This is something that's been discussed, but it's not something we're going to do in the near term. It doesn't rule out the possibility for the future, though.
The reason is that data fields are effectively running along side a native app on the device, which is already using GPS, etc. Data fields already have more restricted memory than other app types, and with the other processes happening during an activity, system resources aren't sufficient to also support communications.
Hello, now we are in 2019, will it be implemented soon? (or may be someone have an idea to mix datafields- speed/distance/heart rate/...- and oauth request without backgrounding?a widget?)
