When you select the "Desktop version" on your mobile phone and you reload or ... from time to time, it changes back to the mobile version of the website. For some websites it's very hard to use them in that way. Especially, when you reselect "desktop version" it isn't reacting anymore. Then you need to close the tab and start a new one.
Would be great if you selecht "desktop version" that it stays that way until you switch back to the mobile version.
