Ratings and reviews

No. Just, no. It went from 5 stars to 1 in one version. The new interface is clunky and cumbersome, and unintuitive. The old interface was perfect, especially if you have multiple accounts. Please bring it back, make a legacy version, something. I am one inch away from going to another app and chalking this into the "Used to be amazing" list.

New interface is awful....now clicking on the hamburger menu shows a pill-style interface, and I can't tell which account I am looking at unless I click through each pill, one at a time. Just an awful change. Not sure how this got past UA testing, but at least give us an option to reskin if there is going to be such a mess to deal with, especially for users who do have mtiplr email accounts.

The new interface is horrible. I have multiple GMail accounts and all I see is GM with no way to tell which is which. I don't memorize the account and color combinations. At least with the old interface I could see the account name and select the account I wanted. I've been a loyal K-9 Mail user for many years but I'm looking for a more user-friendly client now.
