Usage survey - Nextcloud

Please kindly advise how the Usage survey function works? As I try to use it, if I click on “Send new report now” without check any items, the last report box will show nothing.

When I test select one of the items for example “Number of shares”, the last report box will show as below picture.

I am quite curious that if I don’t tick on “send usage survey monthly”, how many days the report will show for (only a current day not sure)? Or If I tick on “send usage survey monthly”, how many days the report will show for (30 days not sure)? Howerver, I test on both tick and untick the “send usage survey monthly” and the report shows the same result. So I have no idea about it.

Thank you in advance.

The box always shows the last report that was sent to our server, doesn’t matter if it was a manual press or automatic sent from the “monthly” checkbox.

If you remove all categories the box is “empty” because that sends to our server that it should delete all your data and that’s happening.
