First Message in thread doesn't update on mobile phone.

[FabienBounoir]

Description

When a thread is created and you're inside it, if the first message is updated within the thread, it won't be updated for other clients on mobile. This is very inconvenient; this bug only occurs on mobile phones; on PC, the message is updated correctly.

Steps to Reproduce

Write a message in a channel with one account, create a thread on this message, and go into the thread with another account. With your main account, update the first message (from the parent channel), and you will see that on your second account, the first message of the thread does not update.

Expected Behavior

It would be normal for the first message of the thread to be updated, as it already is on PC.

Current Behavior

Currently, the first message of the thread is not updated correctly on mobile phones.
