Something has gone wrong...

I have not been able to log in to Revolut with my current device (LG G5 android v 7.0). Had this device for over 3 months now…
Keeps saying something has gone wrong.
I’m on “premier”… I’ve contacted support several times and when they finally reply back to me they cannot help me.
I’ve got the latest version.
Uninstalled and re-installed.
Logged out of old device.
Requested that technical support contact me (such a joke thinking that someone would actually contact me or fix this bug).
Anyway last attempt to sort out this bug before I delete the app.
Need some help here.

With metal launching they have seen increased loads and it have lead to intermittent failures like that throughout the day.
