Row size exceeded the allowed limit.

Row size exceeded the allowed limit.

We have been uploading data to a Zoho Analytics dashboard using a very simple pipe, OneDrive with an Excel doc. Since today we are unable to update the set, and get the error "row size exceeded the allowed limit." Assuming they meant the data allowance had been reached, I was suprised to see that it wasn't, and still have over 500,000 of rows available.

Anyone had this issue before?

PS. The data being uploaded is composed of 22 columns, no formulas, just date, few numerical columns and then string text.
