Display problem on iphone web browser

I’ve had some issues with the iOS app, plus the interface is different. So I prefer to stick with the web app.

When trying to view on my iphone, it only displays a single day at the beginning of the week. When I try to shift the view across the week, it forces the view all the way to the end of the week. It will not allow me to smoothly shift the view from left to right. This also happens when viewing the parking lot. It does this in both portrait and landscape mode. I do not see this issue when viewing on my ipad. 

I have seen this on both iOS 10 & iOS 11. Currently, I am on iOS 11.0.2 and using both Safari and Chrome v61.0.3163.73.
