Person to Person Query Results reduced

Hello,

I have been using the Person to Person query in MS Viva Insights to look at collaboration patterns.  I would run the query for a 6 month period, export the csv file and analyse the results in R studio.  However, in February 25 I noticed the results set was returning fewer rows and now in March I can run the query with no selection made other than a date range and the files empty.  The feedback internally is that there has been no change and other exports such as the Wellbeing and Manager effectiveness return files with 100k plus of rows, but the Person to Person query is no longer working as expected.
