Also, the number of documents shown in this warning was different from what was seen later in the initial replication message “Fetching info (x of y docs) …”:

I noticed some discrepancies in the numbers reported as well! Mainly for numbers in /api/v1/users-info API that I made earlier and then right now using my script.
