Three MAJOR design principles that apply here:
1. Blame the product, not the user
2. Don't fix what ain't broken
3. K.I.S.S. – Keep it simple, stupid
Looking at the vast amount of feedback (and closing/removing threads pinpointing this feedback), people are not happy with the update, and disappointed in the response given when they ask how on earth essential functions have been hidden ("But it's really simple! 🌈💪"), while the most trivial information has been pushed all the way to the front.
Please Bunq. As a long time user I ask you: swallow your pride. Tell us you fucked up. Put this thing in reverse. Go back to where users were ecstatic about the app and your service, and build from there. Honestly, what did you expect?
