Do some people not have "Messenger red notification" enabled?

I've been trying to buy a certain specific type of Bass for around a week and are having two frustratingly slow exchanges with two different sellers.

On both occasions I've been able to see that they were online yet they have not responded to outstanding PM's whilst online. Is it that they don't see that little red envelope symbol or am I just being impatient?

I've resorted to putting " Pm'd" on the actual For Sale thread to try and alert them.

some folk may be on the mobile version which doesn't flash up as obviously.
Some folk just take ages or are busy.
I actually set any PM''s to jump up and show ontop of the page.
but if you want my bass I'll reply as soon as I get it....

By default there will be a red notification. adding 'PM'd' to a thread is a good idea, though. I normally do this anyway.
