I created a spreadsheet in a workspace that was shared with me, but apparently when I do that, I am not assigned as the owner of the spreadsheet I created. I am not able to move that spreadsheet into a workspace within my own account.
I also tried making a copy and saving the copy to my account, but that doesn’t work, either. So, it looks like it is currently not possible to transfer spreadsheets between accounts. Is that correct?
Using another test account, I tried adding the test account as the owner of a spreadsheet, and even though it allowed me to have two people assigned as owners, I still couldn’t copy or move the spreadsheet into the other account’s workspace.
