I was just about to create a post about this too when I came across this one.
Can someone from Monzo comment on this and whether it is something on the roadmap? I too would love to see the ability to restrict types of transactions as mentioned above.
It stops all transactions including Google/Apple Pay. I think the idea is that this way you could pick and choose which transaction methods were active. For example: if you don’t like using contactless you could disable it or if your card goes missing but you still have your phone you could disable all transaction methods except Apple/Google pay.
