No, you don't need to update Bungie about it. Bungie look at more things than just a single location change when figuring out if accounts are being shared/recovered. Potential examples they may use while investigating would be things like: - Is it the same device or a different one - Frequency and timing of location changes, ie is it always a weekend for a trials card you're suddenly signing in from hundreds of miles away and once the card is done you're back on the first device - How many accounts are being signed in to that device that were in other regions hours before - How many different devices in multiple regions is the account being signed into - ie multiple times a week UK, multiple times a week USA, multiple times a day France. Your Steam region can be changed once you use a payment method from that region - you may want to read through [url=https://help.steampowered.com/en/faqs/view/2B3F-DAEF-846B-A0E8]Steams region article[/url] or contact Valve for more information. You should contact them about your preorder though in case changing regions causes any issues there.
