I just went back and read through some of that thread, at one point @Eric mentioned that the chat is limited by design and in certain situations that makes sense. If I am free riding in the jungle I probably shouldn’t see chat messages from someone in the dessert. However, in events I feel that it makes sense to see all the messages regardless of where you are.
Maybe that can be tweaked for the large events and tours where there might be 1,000’s of Zwifters and it could get real messy real fast. But you make a great point about smaller events that can get stretched out, we should still see each others messages.
For reference, the other thread and comments are here: Group ride chat funkiness---can only see some of the messages - #95 by Tony_Agee
