Hi,
I have a problem with my google docs data sources in ARIS MashZone.
I have some (private) google spreadsheets to show in MashApps. In the beginning, they work fine but then they throw some warnings like: A column named "XX" does not exist in the data source.
Then, i go to the data feed, refresh the data source, and everything works fine again.
What could it be the problem?
