Aside from this, I think not being able to have official monzo bank statement as a form of proof of address. I also wish the Android app was more secure (fingerprint scanner) but I understand this feature is on its way.
Apart from the above, I absolutely love my monzo account and for the first time in my life I was EXCITED to start using it and spread the word about it. It’s made life far easier and I can’t wait to see Monzo’s future state. I would say it’s just a matter of time before it becomes my main account in all aspects of my personal banking.
