Dynamics GP 2015 Email Actions for Workflows not working on iPhone

Good morning,

      I have Dynamics GP 2015 14.00.0898.

iPhone for some reason, adds some unwanted text (This is TEXT), removes the option to Approve/Reject the task, and doesn't show the document line items. While the rest of the devices (we tested Android and Windows phones and tablets, and Outlook client), everything is working fine.

Any suggestion is welcome.

Thanks,

  Mr. García
