I'm not able to repro on my iOS 10 phone. Are you sure that the failure isn't iOS 9 only?

I am able to reproduce on my iPhone6s with iOS10.0 latest beta.
Just goto the main page at leisurefitness.com
Tap shop-now and then browse back and forth between few webpages.
Now try scrolling down on any page and you will be redirected to Google Maps automatically.

I was able to reproduce easily just after few minutes surfing on that specific webpage.

Any traction here? It's not a release-blocker, but it's really bad behavior if scrolling can simply cause an app switch without prompting. It's user-hostile. 

I've been testing this and determined that the web site behaved differently between iOS 9 and iOS 10.

I can reproduce the problem on iOS 9.3.5 only. Cannot repro on 10.1.

The web site requests different maps URL on iOS 9 than on iOS 10.

Are you still able to reproduce on iOS 10? (see comment 3)?

I cannot repro on iOS 10.2 but assigning to Srikanthg to verify on his device as well.

I can still reproduce on iOS10.2 dev on iPhone7 with the latest M55 beta.
Let me know if you need anyother info.

Removing M-55 label as we are way past that.
Tested on iOS 10.3 beta and cannot repro, but can still repro on iOS 9.3.

srikanthg: Can you retest this in M58? I think this is the same problem as Issue 700709 which has been fixed.
