Yes, it would be nice to know when/if an attempt was made, but I've been "assuming" it would update one of those fields when it tries. Just below those two, there should be Recent Bounces. A couple of Reasons that show on mine are "554 mtaig-mcb04.mx.aol.com ESMTP not accepting connections" and "force failed". Not sure what that last one means though. I don't remember seeing it before about a week ago. Right now, I'm inclined to think it's related to something in the Groups.io system, so there may be a glitch that Support could fix.
