The contest task is partially completed: stickers, video/voice messages and background animation sending effects are not implemented. The work on the animations editor is not finished. The default speed of message sending effects does not follow the provided mockups. Unfortunately, the app will not be able to receive an award due to the contest task not being completed and due to the numerous issues identified during the testing stage.

More details about the issues we were able to identify: 

Text messages
– When using the reply feature, the original message is zoomed in the preview part of the message bubble.
– After sending a text, its outline appears separately from the message bubble.
– If a pinned message persists in the chat, it will be covered by newly sent messages.
– Large messages are displayed on top of the chat header.

Emoji
– Animated emoji won't start playing until the chat is reopened.
– Editing text messages with an animated emoji will lead to an app crash.

Stickers
– The app crashes after sending static stickers.
