Shared review, receiving notification of comments -- Is this how it works?

I've used (exclusively) email reviews until now, but want to do some shared reviews as well (have started a couple).

The PDF being reviewed is stored on my employer's server.

All my reviewers are on that network so have direct access to the PDF, and I access via VPN.

I'm only on the VPN infrequently.

I see Tracker preferences to automatically check for new comments (1/2/8/24 hours/Never) and display notifications in the system tray and inside Acrobat DC (I've seen the second one work when a comment was received while I was logged on).

QUESTION 1:

As I read those options, I understand that all the 'logic' for sending/receiving notifications is on the *Tracker* side of things. That is, there is nothing in Reader/Acrobat on the *reviewer's* side that initiates notifications, correct? (The only way I could say that it *could* would be if the pdf stored the initiator's email contact. But just want to be sure :-))

QUESTION 2:

*Is* there any way to receive an email when a reviewer publishes comments to the *shared* review (as stated above, I know I can use email reviews instead, but I want to use *shared* reviews)?

(I saw that question in a different post, the response was to use email reviews, and that was the end of the thread -- unfortunately, that doesn't indicate if there is a way to do it in the *shared* review.)

QUESTION 3:

I'm going to start diving through the forum to check, but are there any particular "gotcha's" of which I should be aware with shared reviews as of Acrobat Pro DC 2015.023.20070 (2015 continuous release)?

I'm trying to get buy-in from my SMEs on using the shared reviews, but if it blows up (e.g. loses comments), I know I'll lose their support (the SMEs).

Thanks!
