Hey @lauraeci, sorry you never got a response about this. It's been so long now that I assume you have either moved on or figured it out. As far as I know, external tool assignments are currently working well, but let us know if this is still a problem.

Haha, yeah we've moved on. Thanks @simonista. :)
