Ok, thank you!
But what I don't understand, I have for example an old discussion thread with the last message from me dated Aug 12, 2023, 1:41 PM.
And last seen by the Seller is "39 minuted ago".
So I don't think it concerns the discussion thread itself but last time the Seller went on Fiverr.com. Isn't it?
If the seller has dozens of threads running, how do I know he has seen my last message?
Thank you,
Vincent.
