I had exactly the same problem with Windows 1, nothing I tried worked. I found a work-around by using a mobile device. I have an ipad and a Android phone both linked to my router via wifi. I loaded MyCloud 5 onto both and they now permit sharing by sending links to files/photos. both at home and remotely. I have given up trying to make Win 11 work. WD need to come up with a simple fix, they have remained incredibly quiet about this common problem.
