Share link via email in Safari on iPhone

Hi All

I have created an I Want To... task to share the map view via email using the ShareOn command.  It works fine in desktop and tablets, but for some reason it wont open the email client in Safari on the iPhone. No errors are flagged, it just opens a blank tab and sits there. I installed Chrome on the same phone and its works OK with that Browser, but for some reason it seems to fails with Safari.  I tried playing around with the settings:

- Turned of Block Pop-Ups

- Allowed Cookies

_ Open links in Background & New Tab

None of these seem to work.  Any thought or tips would be greatly appreciated.

Cheers

Chris
