Hello @Itchyfeet As Ben is not online I can help as I can see that this information was given on another thread "Low Applications" Label on Desktop Listings - #22 by Karen_E
The criteria for the low application tag to be applied is
“48hrs low application tag with only 1 applicant”
I believe that the new badge lasts 24 hours after the dates are posted, then there is a period with no badge and then after 48 hours if there 0 or 1 applicant the low badge is applied.
I hope that helps, if you are worried any listings are not showing this correctly then please reach out to membership services with the listing link at support@trustedhousesitters.com
