They should still be there. Kenso keeps your logged sets on your device while you train and syncs them to the server as you go, so backgrounding the app, locking your phone, or taking a call doesn't wipe your workout. Reopening the app should return you to the same session with your sets intact. The real risk is force-quitting the app instead of letting it background normally, or losing connection at the exact moment a set is saving: a few seconds of the very last edit can be missed in that case.
What to do
- Reopen the app and check the workout. Most of the time nothing is lost.
- If one set looks missing, re-enter it rather than restarting the whole workout.
- If the entire workout is gone, rather than a single set, that's a different situation. See pause and resume for what does and doesn't survive an app close.
Contact support if sets are disappearing regularly, not as a one-off.
