UK Ring plug in adapter 1st generation question about voltage

Using the Ring first generation plug in adapter in the UK with the new Ring video doorbell wired which is shown as compatible on the Ring website.The adapter is rated at 24VAC and the Ring video doorbell wired says it’s works with 8-24 VAC so all should be good and it appears to work fine. However when looking in the Ring App it shows the transformer voltage as good at 29V which exceeds the advertised power of the adapter and subsequently the power the doorbell.So is this correct or will 29V damage the Ring video doorbell wired?Any help is greatly appreciated.
