Action Performed:

Precondition: User should be Signed Out

1. Open app
2. Sign In with account where at least one chat with long history
3. Tap on the chat with a long history (Chat should be Uncached)
4. Scroll to the very top
5. Send a message to the chat
6. Return to LHN
7. Tap on the same chat from step 3 again
8. Repeat steps 4-5

Expected Result:

Chat should be scrolled to latest messages when user sent a new message

Actual Result:

The chat does not scroll to the bottom when the user sends a message in step 5. However, when the user navigates to the LHN and then returns in step7-8, the chat scrolls to the bottom after the message is sent. This issue occurs when the user navigates to an uncached chat after signing in.
