Default Customer Address issues in 3.9

There seems to be bugs in the 3.9 version. I have “Hide shipping costs until an address is entered” and have set the default customer address to have Shop base address, only to be able to get the country to show correctly. However it tries to estimate the postage (using Australia Post calculator) based on shop base address, before customer has put in an address.

I previously had the customer location set to Geolocate but changed it because of the warning about Maxmind Geolite info and didn’t have time to investigate what is required.

So question to Woocommerce, is do you need to have the Maxmind Geolite database set up done to be able for it to go back to normal where country is shown and the customer can enter address in before shipping costs are shown.

Also, if you choose No location as default customer location, for Australia, GST is not calculated until address is put in. Needed to change 5 sites to Shop base address for this to work today otherwise all prices were showing without GST included. Granted it was going to be added when customer entered address at checkout.

Is there some good documentation about the significance of Default Customer Location as it is impacting significantly on ecommerce if the incorrect choice is made. Your current documentation has minimal info.
