When I try to connect a google sheet (with the new feature) I get the following:
"Internal Error - An unexpected error occurred and the operation could not be completed"
There is a problem with the specific sheet (it works with other sheets)
There are titles on all of the columns and I tried to change formatting - didn't help
Are you able to access the google sheet directly through a web browser? Also, have you verified that you have the same permissions? If you move the data from that sheet into another sheet that you know works, does an error occur?
