I'm one of the new user here, the Admin staff have assigned me into the group, and shared a link for me to join in, but I still couldn't get access to it. I don't know if it's a technical issue. Looking forward to hearing from you.
Please provide more details on your ask - Examples (What do you mean by Admin staff have assigned you into the group? What group? + Shared a link for joining - What product/application that the link is referring to ?)
We will need a bit more information, so we can advise you better.
Best, Joseph Chung Yin
