Opening a Walkie Talkie conversation in the Magpie app said "This conversation could not be opened. Try again." every time. It opens again.
In a team, the app now shows the team's channel for everyone in the list and People on the team under it: each person's picture, name, and whether they are on Walkie Talkie now or when you last talked. Choosing someone opens your conversation with them, as on the website, so the header action in a team is New group.
