I looked at your activity over the last few weeks and in each of your “log out” sessions, it’s only showing the ride sport, not running. Are you selecting the run sport at the pairing screen? Try closing your Zwift iOS app and then open a fresh session, then select Running as your sport. I don’t recommend switching back and forth between running and cycling in the same session. Force close the app before switching sports.
If that doesn’t help, please submit a support request if you haven’t already done so, and a Zwift team member will be happy to take a closer look at this matter.
