@santhugr8 - again what device and operating system is being used to perform the setup? Apple or Android - model specific and OS version. There is an existing issue that is globally pinned in this community - have you checked that -> 632 Firmware Release Notes for Gen 3 - Impact for onboarding controller using iPhone 11/iOS 13.4.0 & Samsung Galaxy S10/S20
There is a workaround posted there. I have seen iOS work better than Andriod, so if possible try a different device.
