You can pause an activity at any time and come back to it later as long as you do not click the “Withdrawal” button.
If you just want to stop working and return later:
First, click the Save button in the activity to ensure your progress is stored.
Then, use the sidebar navigation — for example, click the Dashboard button — to leave the activity.
By doing this, your progress remains saved and you can resume the activity at any time (see the explanatory images below).
However, if you click the Withdrawal button, a pop-up will appear saying:
“Are you sure you want to withdraw from this activity? This action cannot be undone, and your progress in the activity will be permanently removed.”
If you then click Confirm, your withdrawal is final: all your progress is deleted and you will not be able to resume the activity later (see the explanatory image below).
