I am having some trouble allowing a free (unlicensed) user to edit a Smartsheet. I am a paying licensed member and have shared a sheet with a client and have made them an editor. As far as I can tell, none of the columns or rows of the spreadsheet are locked. When they open the sheet, it shows read only. They are unable to make any edits.
I have tried to delete them and add them again with no luck. What am I missing here? As far as I can tell from reading the permissions documentation, they should be able to edit the sheet as a free user as long as I have them setup as an editor.
Thanks!
