Not a bug Automatic "Watch Thread" after reacting/liking no longer working after upgrading to v2.3.9

Affected version

2.3.9

I recently upgraded my forum from Xenforo 2.2.x to 2.3.8. Since the upgrade, my users have noticed a change in behavior regarding thread watching that feels like a bug or a missing setting.

The Issue:

Before the upgrade (v2.2): When a user "liked" or reacted to a post in a thread, the thread would be automatically added to their Watched Threads list (a bell icon would appear in the thread list). This allowed them to receive notifications for any future replies automatically.

After the upgrade (v2.3.8): Reacting to a post no longer triggers the "Watch Thread" action. Users now have to manually click the "Watch" button at the top of the thread if they want to stay updated.

My Questions:

Is this a known bug in Xenforo 2.3.x, or was this a deliberate change in the core logic?

Is there a new setting or a specific toggle in the Admin Control Panel (ACP) that I might have missed to re-enable this "Watch on Reaction" behavior?

How can I restore the previous functionality? Many of my users rely on this to keep track of active discussions they've engaged with.

Any guidance or advice would be greatly appreciated. Thanks in advance!

Sounds like an add-on.

Sounds like an add-on.

I'd have to agree, I don't recall it ever being the case that a thread was 'watched' just by reacting to it.

I would like to provide an update and clarify the situation. After a thorough investigation, I have confirmed that the "Watch on Reaction" functionality was actually provided by a specific version of an add-on I was using, and it is not a native feature of XenForo 2.2 as I previously thought.

The behavior change occurred because the add-on's functionality shifted or was affected during the migration to v2.3.8, which led to my confusion.

I apologize for the misunderstanding and any inconvenience caused by this report. Thank you all for your helpful replies and for pointing me in the right direction.

To the Moderators: You may now close this bug report/thread as the issue is resolved on my end.

Which add-on?

No apology needed.
