Has the way to block when tagging in changed?

[Itinerant]

I'm pretty sure before the latest patch I'd just hold two fingers down and my characters would come in blocking.

Now it doesn't seem to work and my characters come in doing their attack, or just drop in if a team member was KOd.

It's very frustrating, especially if I've been cornered.

Has something changed or am I doing something wrong?

Edit: Figured it out. Think I was blocking too soon.
