I was just coming to this board to try to find some answers myself. Here it is 2022, almost 2 years after these earlier posts, and I am having some of the same issues. I have a 1900 US Census record that says the record has been removed.
If I approach this record from Arthur's father's detail's page, it seems to link to the record and information (after a quick flash of "Record Removed!"):
However, when I go to attach it, I get this:
What do you suggest? How/when will this be fixed? So frustrating.
@lolski - Unfortunately, this is a known problem. The good news is that the engineers are aware of it and working on it.

Don't use the record that has been removed. When you search you almost always find a valid record.
