A Smartsheet That Cannot be Opened
Update 7/17/18: support "refreshed my sheet and account settings on the back end" and that fixed my problem.
I have a sheet named "Dashboard" that displays all sorts of summary information from other sheets in my application. Suddenly a few days ago it will no longer open and generates an error message that logging out, restarting Chrome or rebooting my Mac doesn't fix. I sent an email to Smartsheet Support a few days ago but so far they haven't responded. Anything I try to do with the sheet (open, copy, export to Excel) generates the same error message. I have about 80 other sheets that all seem to be working just fine. Any thoughts?
I just noticed that this problem is apparently causing my weekly automated backup of all my sheets to fail.
