Is this with the default sandbox location? 
This is not the default Location of Sandbox. This is the Location I created a month ago. Now I can’t update the information of Location because there is an exception in the Square Address API.
What’s your application ID and what is the address your trying to change the location to?
We have exactly the same issue. And we’re not trying change the address.
Your endpoint is just returning 404
You actually can’t create location due the same error.

What’s your application ID?
This is not an API call. I’m on your web-site. (Sandbox 1DMLMPG6109HFZ0)
Oh, okay. Many of the UI features aren’t currently feature complete and won’t work. If you use the API it will work as expected.
