I use just about all of the features, and honestly have not had much problem with the update. I was able to find everything I was looking for on the same day that I got the update simply by playing with the app and tapping on everything to see what it did.
I'm sorry but I'm not sure you do use 'just about all of the features', if you did you'd notice that no amount of tapping will find you what's missing from this update....
As a few examples:
I ride bikes at the weekends & frequently save a route in My Maps to follow while I'm out. Can I still find this? Nope.
Can I check elevations to see what kind of hills or descents I've got coming up? Nope.
I cover a huge part of the UK for my job & have my journey plans saved as Maps, can I still access them? Nope.
I could save a point on the map as a star even if it was in the middle of nowhere and navigate to it, handy for my work & when out riding. These don't appear in the app now though....
When I visit a new site for the first time it's very easy for me to highlight them on the old Maps & use my menu button to add as a contact. Now not possible unless you know different?
I used to be able to use Navigation direct to these contacts from my dialler/people app, that's gone now though right?
Sometimes I don't need to use Maps, I just want to use Navigation as a separate app or check traffic nearby. Not sure that's an option now?
Admittedly some of these might not be mainstream functions the masses use to the extent I do but they are a key factor in me staying with Android. I personally can't stand iOS so to have our beloved app 'brought in line' with the iPhone version seriously sticks in my craw. There's a few very good reasons why Apple is quite unpopular with some & yet Google seems to be going down the same route....
And FYI I've let the Devs know all this but I've also been monitoring the reviews on Play... Almost 7k 1 stars since Wednesday with another 30k 2 or 3 stars in the same time. Pretty epic fail if you ask me.
For the record I do really like the look of the app in some parts, I just cannot for the life of me understand why so much has been stripped out. And that's without even mentioning the numerous bugs that point to this being a very early beta....
