Describe the Bug:

My nephew made this group chat and the first message he did not receive (hello hello). When he posts messages I see them double. When I DM him its normal.
Edit: dhdh and Halloween also double. This screenshot was a little outdated.

Here is his side of the conversation. Same App version etc, also Andriod.
