The onboarding link expired 24hrs after it was generated. In addition to this, the vendor will only be able to reopen a link with the same device they opened it with the first time. The vendor can refresh their onboarding link with no external help needed via his onboarding.

For example, if the link was first opened with device ‘A’ and it is attempted to be opened later with device ‘B’, the link will be expired. When the vendor refreshes the link, it can be again initially opened from any device.
