AirPods Pro 2 update Problems ios26

I have new AirPods Pro 2 with firmware 7B21 and an iPhone 13 with 26.0.1. I have been trying to update the AirPods for several days now, following the instructions (About firmware updates for AirPods - Apple Support). In the meantime, I have also reset them, reconnected them, etc. The Wi-Fi connection is stable and both devices are fully charged. Nothing is happening…
