It seems like Revolut’s latest Android update (6th November) has shafted some users, including me, rendering them unable to receive the update, and making the app disappear entirely from the Play Store for those users. No notification, no warning. Just a sudden stop to updates. I had to restore from a backup I made of the app, and was then able to transfer my money out of there.
I spoke to support, and their suggestion? Use a newer device.
I guess I will be closing my Revolut account.
