There seems to be a defect when People Picker fields in SharePoint are used with Environment Variables in SharePoint.
The solution imports into the environment fine and connects to the new SharePoint Sites and Lists but the People Picker fields will not function. They become unsearchable and can not connect to any data. They will display any existing data from the SharePoint list but new data can not be entered and existing data can not be updated. An error message is displayed saying the list can not be found.
I've ran multiple tests and have asked colleagues to do the same and our results are consistent. The People Picker field does not function when used with Environment Variables.
Hoping this can be addressed by Microsoft so we can use this functionality in our environment.
