Sorting of visual is changed for other users in app

[Anonymous]

Hi,

I have a column-visual with dates on the x-axis with drill down functionality on year, month, day and hour. In desktop I have set the "sort axis" option to sort by the dates and the visuals are sorted according to the dates. When I upload to powerBI service and publish in an app however, the x-axis is sorted correctly for me. But for my colleague, the axis is sorted on the y-axis values. 

In the app I cannot find any options to change the sorting, do you have any suggestions?

Thanks in advance!

Report users can change the sort column and direction.  Ask your users to reset the page to the default settings.
