Hey, thanks for the report. This is a known issue.
In the meantime, here’s a workaround:
The problem is that if you archive a pinned chat, it still counts toward the pinned chat limit (even if it’s not visible). Fix:
- Open the Archived section in the sidebar
- Right-click the archived chats and select Unpin (if they were pinned)
- After that, you should be able to pin new chats

Let me know if the workaround doesn’t help.
