Fail to start the test on windows 11

We could not conduct the whole test, it fails to access the camera on windows 11: impossible to click on the « yes » button to allow the access. Then the whole test can not be conducted…

Betrug

Achtung, dieser Test grenzt an Betrug. Diese App hier existiert einzig, um die Testumgebung vor Durchführung des Tests zu prüfen. Ich habe, wie andere hier auch, alle Vorgaben befolgt und habe durch die App in jedem Schritt eine Genehmigung bekommen sodass der Test beginnen durfte. Dennoch erhalte ich nun die Benachrichtigung ich hätte Hilfe von Dritten bekommen, was nicht stimmt. Ich habe 70$ bezahlt, bekomme kein Ergebnis und mein Guthaben um den Test zu wiederholen wurde wegen des angeblichen „Regelverstoßes“ ebenfalls gelöscht. Das ist eine Betrugsmasche. Und man denke bloß nicht dass nach dieser Willkür irgendein echter Mensch im Kundenservice aufzufinden sei. Müll. Dass dieser Test überwiegend von jungen, mittellosen Menschen gemacht wird, scheint egal zu sein. Geld weg, Guthaben weg (eigentlich hat man drei Versuche) und niemand spricht mit dir. Hinterhältig.
