How can I make changes to a running psychopy experiment?

URL of experiment: personalauswahl [PsychoPy]

Description of the problem: My experiment is running since this morning. A participant found a little mistake. I had to fix it (labels of one rating scale) and uploaded the new version successfully to gitlab but the old version still appears when I follow the link above. I tried to switch to Piloting again, but this is not working too.

What can I do to synchronize changes to a running PsychoPy experiment?

Thanks!!

Ask the participant to use Ctrl-Shift-R or an incognito tab to view the latest version

Thanks for the quick answer!

I tried clearing the cache and the incognito tab too, both is unfortunatly not helping…
