Signed out with 'This business account is currently suspended'

When Kaydro suspends a company, its people are signed out at once, on their next click, page or till sync. A screen left open checks every minute, so within a minute it goes to the sign-in page with this message, and nobody can sign in again. Contact Kaydro to sort out the account.

A till with no internet keeps selling, and is signed out when its connection returns.

If the message says This account has been disabled, only your own login was switched off. Ask your manager to check Settings → Staff.
