In Team Duels, add chat to the replay
Neuer3
In Moving Team Duels, I sometimes write town names or other information I find into the chat so my partner can also scan for them. Because you can't see the chat in replays, it just looks like a brief pause, staring at a sign and inexperienced players might conclude it's googling or something like that, so it would be nice if the chat were visible to clear up what's actually happening.
Vols and Jezuz
Clearly they can't just show everyone's private chats, but they could have it pop up a little keyboard animation when a player is typing. Or even just like Steam and say "so and so is typing...". That way it won't look like the player is just looking stuff up on their phone. But cheaters could also abuse this by pressing random keys on the keyboard while they are using their phone, so idk probably not worth the effort to implement.

Not all communication in the chat is of a strictly game-related nature. It's at the very least dubious with regards to data and privacy protection laws (like GDPR) to save the chat and release it for everyone to see. Thus, I think the cure is worse than the disease.
