Accepting a walk can be achieved by clicking the accept button located at the bottom of a walk request.
Once the booked time of the walk is reached, a walk will be startable, by viewing the walk and clicking "Start walk". It is important to start the walk at the requested walk time.
Once a walk has started you will be able to do the following inside the active walk screen:
See the walk map (which has live tracking).
See photo requests from the walk events modal.
Log toilet breaks.
Log pee breaks.
Send in-walk photos to show off the adventure you are on.
End the walk.
When a walk has been completed, there will be a walk review and summary. With all of this completed, you've not successfully completed a walk! Congratulations!
