@Pain-blue-quokka#138699 Hey Peter! I truly believe you only meant it in a good way, but getting people to allow installs from unknown sources for an APK for a banking app outside the Play Store isn't really something a bank should do.
I get, that it's for emergencies only, but nasty people are constantly trying to trick people into installing apps from outside the play store, especially manipulated banking apps, and I think it doesn't help if the bank itself asks users to disable this security feature and get them to install the banking app from outside the play store.
It also might triggers fake websites claiming to fix issues with an external APK in the future, as bunq did in the past.
I don't believe this will happen today, you're probably not big enough (yet) that nasty people are checking together every 10 minutes, but who knows how big you are in a few years! :)
And I know it's for emergencies only, but bunq Web should really be enough, and the post (https://together.bunq.com/d/23920-update-fixing-android-bug-app-not-opening) doesn't really make it look like it's dangerous to do it (and doesn't even link the https version of the link).
PS: Google Pay Top Ups would be nice for Android! :) Paying with G Pay in Apps is even supported outside of G Pay Tap&Pay countries :)
