LastPass website - can't enroll a yubukey, update button doesn't work.

[alexbal]

As per subject (i have last pass premium).

Can't enroll yubikey - the yubi key succesfully populates the yubikey #1 field.

However the update button does nothing when clicked - it doesn't generate any messages in F12 network panel
