When working, it seems to be quicker when moving from tab to tab. Like most software updates, most of it is probably "under the hood" and often fixes things that you may, or may not, be seeing. This seems to be the first time I've seen them try to push out the Maps update (far more data than the OS) which seems to be at least part of the cause of the issues. Maybe this is a "test" of their Over The Air (OTA) update technology/processes for the new F150 and Mach-e.
If so, I'd say it is not working well ...
