You now have the option to launch the app and open a specific form/dispatch simply by clicking a link from your dispatch email.
You have a few options on how you can set this up.
All of them require you to enter one of the following in your email:
Reference ID: FastField://OpenDispatchWithReferenceId/referenceId
Dispatch ID: FastField://OpenDispatch/dispatchId
Form ID: FastField://OpenForm/formId
Note that in all of these, you must replace the ending with the actual ID's.
Once this has been done you will be able to send the dispatch/email and open the form directly from tapping on the link from your IOS device.
