I’m not sure on the current logic but sometimes they disappear, making it hard to see which posts have a reply we still need to deal with and which are replies we replied to but might want to follow up later to.
What I understand is that when the Glow isn’t visible then the OP is the one who last replied.
Oops, My bad!
The Glow is actually shown on The Post creator is the person who did the most recent reply.
Otherwise, the last avatar on right will be the one who posted last.
Ah fair enough. Our problem is that we have quite a few things in our support and sales list that are awaiting replies from the customer and easily spotting them is quite hard.
