I have a related table that is referenced in my dashboard for multiple elements (multiple charts and lists). All of these elements now has a yellow triangle error that says 'Cannot Access Data'. I have not worked on this dashboard in a couple of months. The only change to the related table has been the amount of data that it contains. There are over 8400 records to date, and I'm expecting to double that number in the coming months. Could the number of records be causing my error? What else should I check?
