"You can't see this image because it comes from a private source"
I am making a Mural (Mural A). Within this Mural I share links to other Murals (Mural B & C). My team starts together in Mural A. Later we split up in two groups. One group clicks on Mural B and the other on Mural C.
In Mural A I place the links to Mural B and C. Both Mural B and C are in the same workspace and even in the same room. But Mural B and C appear differently in Mural A. (see screenshot). The link to Mural B shows a picture of Mural B. The link to Mural C shows a blank picture with the text: "You can't see this image because it comes from a private source". The link works, but it doesn't look nice.
Am I doing something wrong?
Thanks for your help!
