The G Suite (now Google Workplace) admin console GUI is also pretty slow. What makes it worse is that you have no other choice - it's the only complete tool for administrating G Suite. There are APIs for some things, but quite a lot is only available in the GUI, and new features always show up there first (if they ever make it to the API at all).
There isn't even a way to import/export settings, so you have to painstakingly document everything and reconfigure it manually if you need to create a new instance. It makes things pretty painful from a compliance point of view.
G Suite is the worst piece of shit I have to use in my work and I curse the developers every time I'm forced to use it. It's like they went out of their way to make the worst design choices at every point. It would be impressive if it wasn't so depressing.
I can't even get through to G Suite support lately since the only way is through the admin console chat bot, which is bugged and freezes at "transfer me to Cloud Support". Absolutely one of the worst products I have to use on a day-to-day basis.
