Money app Revolut says it is investigating 'issues' with some of its services.
Some users have reported a delay in the app updating itself after a purchase, as well as trouble logging in.
The company says: "We're aware of the issue, and we're working on getting it sorted as soon as we can."

According to a status update, six services are "partially unavailable".
This includes sign in, card payments, topping up and transfers.
It comes as people take to the streets, and their smartphones, for Black Friday shopping.
Revolut is also partnering with 'The Late Late Toy Show' on Friday for charity donations.
