The issue B is now tracked by  crbug.com/663751 
Leave the ticket open as I can still repo the issue A with 57.0.2943.0

Also, reassign it to msarda@ as the new identity team.

 Issue 671388  has been merged into this issue.

This is definitely higher than P3 (at least P2). When signing in with a corp account right now (I assume this applies to other dasher accounts as well), if the user clicks "Create new profile," sync won't start until they manually go to settings. It's not even surfaced as an error, so users may not even realize sync isn't working.

Mihai, we should have the same behavior here that I've described in Issue 661307 (for consumer accounts). When the user clicks "Create new profile," we should create a new profile, open a new window in that profile on the NTP, and immediately pop up the sync confirmation dialogue for the user to confirm sync settings before it starts.

Clicking "OK, GOT IT" should start syncing. Clicking "Settings" should go to sync settings so the user can configure settings before sync starts. Clicking "UNDO" should cancel the sign in (and, if possible, delete the newly created profile).

Let me know if you have any questions.

I guess technically my comment applies to  Issue 663751 . But really both scenarios (A and B) seem important to fix.

I think this bug and  Issue 663751  have the same root cause.

It seems there was a problem when lading CL https://codereview.chromium.org/2594703002/ that reverted the CL above. I'll prepare a new CL with the same fix.

This CL removes the temporary hack to disable the sync confirmaton page
on linux and windows as the sync confirmation dialog is browser modal on

Can we mark this as Fixed now, Mihai?

It is fixed for Windows (not for macOS). However we're tracking mac in a different bug.

 Issue 678987  has been merged into this issue.
