Quality of Office 365 support is sinking..

Yes, I've noticed the same problem after help center modernization. When function of choosing category and subcategory in the support ticket has been retired - the level of support dropped dramatically. Before it took more time to create a ticket, to choose a proper category and make detailed description of the issue, but it was worth the effort. I had always quality responses and fast call-back, sometimes even no call just email where were fixes to my issue.

Now you need to repeat several times your issue, screen sharing session and still sometimes engineers don't understand your issue or ask you to do elementary fix steps which you've already did, and described that you did.

I would love to have back old help center experience.

Other thing that annoys me, it's  when support engineers is asking you to rate their support level while the session isn't closed, and waiting on the line, looking on your screen which rate you will give.
