hello everyone
When a city is selected at the bottom of the page, it can no longer be changed unless a new city is selected, and does not display the default city on the first page.
When the city is selected, if you come to the first page where the search box is there, not only does the city not show, but it only makes Cashe the city ,there is only way you can get rid of that chosen city  when the cache is cleared.
any idea about that ?
Thanks
