A call-only guest invited into a Link meets the same rules as the conversation’s members: a ban, a timeout or a name rule keeps them out of the call and takes them out if they are already in it, and nobody is asked into a direct or group conversation’s Link who is in a block with someone in it. The person inviting is never told which.
On a phone with large text, people’s names and usernames wrap instead of being cut short when you invite to a Link, add people to a channel or a group conversation, share a channel or start a new message. If your own recording of a Link was left running by a tab that closed, the call bar on a phone and the Link’s foot in the sidebar offer Stop recording.
