Account signed in on multiple devices show up as two different contacts in Group Chat

[tiffrobo]

One account on the staging server signed in on two devices: iPhone6 and iPad. (Account name-Jasmine)

Happening when both devices are online at the same time and chats are sent to a group

• The iPad goes into airplane mode.
• The iPhone6 made friends, created a group and started chatting in groups and single chats.
• The second device, the iPad comes back online as Jasmine's account.
• All contacts and group chats were synced.
• iPad sends a chat to the same group iPhone was chatting in.
• The iPad and iPhone show Jasmine chatting twice in the group chat--both as sender and receiver.
• Jasmine is only shown once on the member's list for the group.
• Text, audio and photo chats show up as sender and receiver.

The messages only show twice in the chat view for the person sending the message. Other people in the group only see it once.

I think it's because technically, from the perspective of the room, there are two different occupants that just happen to share a JID. In "anonymous" rooms the occupants real JID is not exposed, so occupants are distinguised only by nickname, which is unique per occupant in the room. We only use non-anonymous rooms, but when you have two devices on the same JID, they still must have different room nicknames.

We'll have to re-think how we handle room occupants a bit.

Should be handled in 118.

I just saw this issue in build 124. I think it's the same thing, except I'm only signed in on one device. However, the group members list shows me twice. Once as me(@staging.zom) and once with @conference.zom.im.

I've only seen it happen once with duplicate messages showing in the chat. This is a new group (created today). However, I do see myself listed twice in a few other group members' list, which are older groups. Once as me (@staging.zom) and once as @conference.zom.im

Here are the screenshots:
