This sounds interesting but here's what I experience: I put London and pressed continue - nothing happened. I gave the location permission and pressed continue - nothing happened again.
Console printed these logs: Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'relativeLocation') at ws.min.js?_=5.21.3:1:133923 at ws.min.js?_=5.21.3:1:89730
Someone posted the international version elsewhere in this page.
