Hi, Justin.
I've put up 2 tests:
www.ponka-wonka.com/phone-bad/index.hmtl
www.ponka-wonka.com/tablet-bad/index.html
As far as I can determine, this weird miniaturizing only affects iPhone and iPad users. We've tested it on iOS 8.3 ... but it could have been there before and just not noticed.
These are multi-device WebApps. And I do not have the same problem with my Android phone or tablet.
The only way around it that I've found is to use a Viewpoint of 100% Zoom, but that limits the flexibility.
And ideas?
If you need any more information, just let me know.
Thanks.
