Facebook Marketplace: Deleting messages from people no longer interested in item

Question

I have items with many replies (what are they called? messages, threads, ???) most of which are dead ends (people not interested, too far away, changed mind, etc.)

How do I "cull the dead wood" replies?

Lots of message help says hover over the Gear and click Delete. No such option is available in Marketplace replies.

NOTE: There doesn't appear to be any way to flag them which would help immensely?

Answer 1

You have to access the messages on a PC, it won't let you do it from a phone. If you pull up the messages on an actual computer it has the gear to delete the messages right by the sellers name.
