It sucks. The old format was less confusing and easier to read. This new format looks like a less understandable version of the new outlook, which is also confusing for the eye. Also, it appears to have lost some functionality. I can't say for sure yet because it is hard to find the functions. I used to be able to use the app in lieu of the website, but now I think I will never use the app. There should be an option to opt out of the change (and its a change, not an upgrade). I hate it.
