I’ve posted a more extensive comment earlier to which I would like to add a small opinion after using the app for a little longer:
I find that some of the menus required a few too many clicks. For example, if I want to see my cardnumber I have to click on the me tab, the cards, my card and then the number and then back a few times to get back.
Something that was nice about the old app was that the bottom menu often stayed fixed in place. With the new version the menu disappears, which makes it a bit more effort to return to the basic screens.
Hopefully bunq can look into this :)
