@mentions not adding users to channels

Prior to our latest update, when we mentioned a user in a public channel that they were not a member of, the act of mentioning them would both add them to the channel and notify them of the @mention.

Since out latest update, that doesn’t happen. If you @mention a user, they don’t get notified, and unless you go looking at the member list to find out if they’re already a member or not, you have no way of knowing that they don’t know!

Is this a new feature? or a setting that has changed?

We are on version 0.69.2

Hmm, looks like this is addressed in 0.70.0 and https://github.com/RocketChat/Rocket.Chat/pull/12168
