If you had updated your Classification Rules 2 days ago, then I would expect you to be able to see the results by now.
Some reasons that you don't:
- If you're using regular expressions in your Rules, then the expressions might have been defined wrongly.
- There is whitespace in your key values.
- You didn't set the lookback window far enough. For example, if your lookback window is for 1 month, but the report that you're running is for data from 3 months ago, then that old data would not be classified.
- You're classifying non-English characters. I encountered this recently. The fix was to use Classifications Importer to import my classifications, ensuring that I specified "v2.1" in the classifications file.
To see what have been classified already: export your classifications (from Classifications Importer) and check the resulting classifications.
