@javier Now website works how it is supposed to for me.
One thing I noticed is that the problem keep occuring on my phone (application). Then I decided to delete the application and dowload it again. But after I deleted it I couldn't get it back because it gave me the warning '' your phone is not compatible with this version ''. So I believe maybe the problem happens with people who has old smartphones. Since application can not be updated maybe algorithym also doesn't update itself and get syncronised like that with the website.
