Hi 👋 Henrik
First of all I don't think bunq has Instant Payments live yet to N26 as they will probably post a notice here as it's a hot topic. It's possible the flash icon appears after closing the bunq app and opening it again, at least that's my experience with other Instant Payments. Perhaps refreshing the events list is enough.
I don't think N26 is correct about only being able to process Instant Payments between those hours as it would kill the whole idea of Instant Payments being processed 24/7/365. Also nothing is mentioned in that regard on their info page about Instant Payments.
I will sent feedback to our contact regarding the information provided by the bunq support team.
Also, bunq will mention in this topic when they will go live with Instant Payments to N26 so it's not necessary to try and test it everyday until then.
