On normal occassions after importing TXT/XML files into a table (either few rows or tens of thousands of rows) normally it should get updated/refreshed immediately, then subsequently the chart will get updated.

But I've experience few times when it doesn't update/refreshed immediately after importing, even with 100% successful and after more than 30-60 minutes. I did reloading, refreshing, etc but nothing happened. Number of rows (bottom right corner information when opening a table) shows the same number, as if it wasn't imported. One time it took the following day I see new data get refreshed. Is there any specific schedule INTERNALLY within Zoho Analytics for the imported data into a table to get refreshed?
