Fixed in this update

• Photos now send and receive properly. Sending an image failed with an error; that's fixed, and received pictures display correctly.

• Voice messages sent to your number now appear as a playable attachment instead of a broken image.

• Calls no longer get stuck. If a call failed to connect, every call afterwards would fail until you restarted the app. Fixed.

• Messages no longer go missing. When several messages arrived at once, one could be silently dropped. All messages are now delivered reliably.

• Buying call credits works again on iPhone.

• Fewer duplicate notifications — some messages triggered several alerts for the same message.

• Going back from a conversation now returns to your message list instead of the home screen.

Thanks to everyone who reported these.
