We've been able to deploy our iOS App to App Store Connect but the process is very strict and we fear that it will be a mess when we will have to fix some bugs. When I'm using XCode, I see it is possible to choose Entreprise as a method of distribution : 
If I understand it correctly, the users can download directly the IPA file stored somewhere on a server with this method,. I'm wondering if SOTI is able to download that IPA file and deploy it on our devices using this method ? I ask because in the SOTI documentations, I've found this :
https://soti.net/mc/help/v14.1/en/console/data/sotihub/hub_deploy_app_packages.html
Where I can read that :
Note: This procedure is only applicable to Android (4.1+) devices. While the SOTI Hub app is available on iOS devices, Apple's security restrictions prevent SOTI from providing an
.ipafile outside of the Apple App Store.
So, is it possible to find an easier solution than uploading the app to App Store Connect ?
