Don't worry, we'll help you out along the way.
I'll keep exploring Motivity.
See the programs that exist in a period (e.g. event or session), click on the start button and a popup will appear showing the current programs and targets and the current phase they are in. To start that session, click on “start session”.
If a session was closed on accident, you can restart the session by clicking on the start button and tap the orange bar to resume the session. To start a new session, click on the blue button.
When you need to transition multiple targets to a target phase (e.g. complete or inactive) you can now click on a dropdown and to transition a set of targets or multiple sets of targets at a time instead of transitioning one at a time.
