Elias I don't use Revolut. The instant payments at bunq are still working fine of course. Because bunq uses both the TIPS and RT1 network for instant payments for both incoming and outgoing payments, the coverage is better than at most other banks.
Only for Dutch customers it might be less good, because Dutch banks also have their own systems and most of them don't participate in the bigger European instant payment schemes. Not really an issue for me as a non-Dutchie though, I'd rather have more overall coverage.
