Hello Kongyan4696,
You are currently in direct contact with our support team.
It is not relevant to duplicate the threads, one with the team and one on the support forum.
In order to save time for everyone, we will close the topics on the forum.
Best regards,
Etienne
Thanks for your reply, the forum is public, maybe it can help others who encounter similar problems. :)
