This is a good one. I started a chat because IFTTT stopped working. On the advice in the Monzo Chat, I deleted my Monzo app and reinstalled it but it doesn’t work because it won’t recognise my phone.
I am currently running an iphone under IOS 12.1.4. I can’t tell you the App version as I can’t open it but it must the be the latest as it has just come off the App Store.
I have attached screenshots.
