I managed to log in, but the system is pretty barebones.

Trying to change or apply for a new banking product just takes you to a help page saying the ability to do this is 'Coming soon'. (Some other features are scheduled to be available by the 'End of April', for comparison.)

Also, in the 'pending transactions' popdown, e.g. £38.60 is displayed as '38.6'...

That implies the balances are being represented as floats and turned directly into strings ... how does something that basic happen at all? Is Sabadell's Spanish web UI like that too? No wonder they're screwed

Javascript only has floats. For the unwary this is a common source of bugs in frontends to financial systems.

Hopefully the backend is using some kind of decimal type.
