Warzone told me, that there are 216 new clan messages, however, when I opened the clan chat, I could only see 100.

Whats the bug here? You have 216 unread messages, but chat only allows you to read the last 100. That leaves you with the information that you missed 116 messages that you cant read anymore.

EDIT: if you restart the app, it should show 100 unread messages again, and not the 216.

One would think that if it says 216 unread messages, you can actually see 216 unread messages.

I bet if you send this as an actual bug report it would get fixed
