I need to refresh 2 times to load entire scheduler on iphone

Page works perfect on pc and mac. However on iphone/ipad I don’t see anything after load. After refresh i can see top bar and after another refresh i can see entire scheduler. When I quit page the same thing happens. Default view is timeline but on different that thing happens as well.

Do you have any idea how to fix it?

does this happens on our online samples?
For example, this page
docs.dhtmlx.com/scheduler/sample … lines.html

If the problem could be seen only on particular pages of your app, link to that page could help us to figure out the solution
