I'll try to keep my feedback constructive - I wouldn't use the word "amazing" to describe V3. I'm a firm believer in accessing the most important things in as few taps as possible and I feel like efficient use of the app has been completely disregarded in favour of pushing marketing front and centre, and as a paying user I do find this a little insulting.
The bubbles on the front page are a perfect example of marketing form over app function, and it gets very confusing how cards and bank accounts are all bundled into the same location, as they are two separate things.
Also the Us tab is just completely useless and I'd love to have an option to disable it. It's just plain marketing and you've already got me as a loyal user, please stop. If you want a place to make announcements about new features and things that are happening, blend them into the interface as they're released.
It took me 15 minutes to figure out how to adjust my recurring payments after spending 10 minutes figuring out how to access customer support.
I still haven't figured out how to manually start NFC payments on the Android app, I can only use the option for it to automatically start. I like to be able to give my fingerprint before even tapping it against the reader, as this speeds things up for me.
If I had the option to revert to V2, I would. I've considered going and manually downloading the V2 app again, but I don't over security concerns.
