On iPad, I think full screen works better for chat than the drawer mode. We’re discussing how best to address that, but you may recommend that to folks who bump into this issue in the meantime.
There are a couple settings here. Are you referring to the “chat max direct message users” setting?
0 is a bit of an odd setting, but we allow it as we know people do appreciate using DMs to themselves as a quick way to keep little notes. Perhaps in your case if you really wish to disable direct messages, you can limit “direct message enabled groups” instead?
