2 days ago our previously working DCM connections have stopped pulling in data and are now giving the error of "Query failed: An unexpected error has occurred, we have logged the issue and will look into the problem."
It looks like this has happened before, however this one hasn't fixed itself yet. https://support.supermetrics.com/support/discussions/topics/19000017767
We're a Super Pro user and this is currently affecting 4 separate queries on 4 separate Google Sheets.
Thanks for reporting this. Very sorry for the error.
It was a bug within our system, that is now fixed.
Please let us know if you still see any errors.
