Here’s one that happened recently. Just because you don’t personally see them, doesn’t mean that they don’t happen. And if you look at the harassment that that the CM had to endure, it’s no wonder really why they do not communicate here more often.
CMs aren’t developers. The developers typically don’t respond here. Why do you need to have a conversation with developers anyhow? If you leave feedback, it will eventually, in some form, get back to them. That’s how it works.
Do you have a screenshot of this? Because you certainly aren’t entitled to conversations with the Devs on these forums. You might have misquoted there.
