Ring doorbell not working after power cut

Hiya. So last week we had a power cut and the ring doorbell stayed offline for 2 hours after the power came back. Everything worked fine again for 36 hours and then the doorbell was back offline when we went on holiday. I got back to find that 6a circuit breaker (powering our two downstairs lights on too) had failed. I moved the cables to a spare 6a breaker and my lights have come back on but my doorbell remains dead. I don’t seem to be getting power to the doorbell. Is it possible it needs hours to charge back up and work again or could the transformer have been fried by the power cut last week? I’m at a loss. Thank you.
