welcome to the forum ,at certain times of the day the internet is becoming swamped due to the number of people that are using it during lockdown ,i have found the best time to do stuff like this is early morning or late at night ,
Thanks I have tried that with no luck, was worth trying though.One thing you can try: if you are using WiFi, try turning it off on your phone and using cell data instead. (or the opposite, if you were trying cell data, enable WiFi). This might help if there is a network issue during activation.
