Hi @AB_BriSeck
thank you.
I had already deleted the WEBDAV share on the NAS and then set it up again, but not on all devices. I will now try again. for the demo account I had already found a tutorial in the support, can you send me the link please, because I can no longer find the post. How do I send you the demo data. I would not like to write them here simply in the post. Thanks for your support
