The current report only shows number of reviews we replied to from the feedback that came in that same day. The report that we are looking for was available on Feefo V.1 and was called Housekeeping Report. We desperately need this report back on as it is too much of a hassle trying to count our responses manually.
We have investigated the problem and there is a bug on the Activity Summary Report. We have raised this as an issue and will keep you updated on progress and planned release dates for the fix.
