I just realized that sites done in Webflow doesn't display properly on iPhone 5 devices. I don't know if this is the same for all iPhone devices since I have only 5 and 5C to check, but once I'll get to 3GS my friend have Ill check on that too.
The issue is that sites done in webflow when opened on iPhone 5 they are
460x320px portrait and
156x320 landscape!!! I just checked on my private server (http://bartekkustra.eu/dupa.html) that browser opens with
1409x980px portrait and
553x980px landscape. It seems that Webflow have some issues with iPhone browsers. I checked both Safari and Chrome on my iPhone. I think this is something you should work on quickly.
