iCloud blocking Wi-Fi on new iPad after account recovery

I have recently replaced my IPAD7 but once set new one no worries with Wifi until I recover my ICloud account on it. Then, Wifi is not recognised as safe to use, many APP unavailable (Bank, Messenger…) How can I find my way for my iCloud to stop blocking the Wifi?
