With our new update you'll be able to hide open feedback time stamps in your shared reports! This makes feedback anonymity even more secure, especially when there aren't that many results on a report.
When creating your shared report, you'll see Hide feedback timestamps added as the last View Option. Just select that and the time stamps will be hidden. This option can also be added to already created reports by editing them.
Note that you will still see the time stamps in Feedbackly Analytics, and the changes will effect only shared reports.
