Application Configuration using XML for iOS devices

Hello there, I have been trying to push out and make available in the Application Catalog an app called SecurePIM (version 7.75.2) to a set of test iOS (12.1.3) devices in our environment. SecurePIM is pushed automatically and works fine until I try to use the Application Configuration (xml) option to push out predefined settings such as the license code, the email address, etc. You will find my xml below:<dict> <recipientCertificateEmail>helpdesk@company</recipientCertificateEmail> <deviceSerialNumber>%SERIALNUM%</deviceSerialNumber> <license>license number goes in here</license> <userEmail>%ENROLLEDUSER_EMAIL%</userEmail> <activeSyncUser>domain\%ENROLLEDUSER_USERNAME%</activeSyncUser> <activeSyncServer>server goes in here</activeSyncServer></dict> I noticed that if I add the proper xml headers, I get a error message stating "The configuration command you entered must have 'dict' as the root node. Please check your configuration and try again".... hence the <dict></dict> tags and no <?xml version="1.0" encoding="UTF-8"?>. The other tags are specific to SecurePIM. SecurePIM requires the end user to register their app and type in their email address and password before they are able to use this app. The idea behind using the xml is to streamline this process so all users need to do is type their password and the app would be pre-registered. I have been in discussions with our SecurePIM reseller who told me (and even showed me official how-to documents) on how to get this feature working in other MDM, however they have not worked with SOTI previously so weren't able to assist me.  It is worth noting that when attempting to use xml application configurations, the app itself does not get pushed to the devices nor am I able to install it via the Application Catalog even though it is there.I am hoping that a SOTI team member or a forum member has had some experience with application configuration xml for iOS devices and are able to shed some light on the problem. This is my first time attempting to pre-configure an app that we want to make available for our users. Happy to provide any further information as required to hopefully get a solution to the problem. Thanks in advance.
