The Data Collector RemoteUI type doesn't seem to launch the same set of views as it did before upgrading. The user is seeing a view called the Regular UI panel instead of the Data Collector one we were seeing before we upgraded.
APM has made some changes to how we set-up the information displayed for the APM Remote users and what information is downloaded to the APM Remote Client in the last few versions of APM.From what is described, you may need to update both the user's Alternative UI type and the Download Package used for the APM Remote client.
Firstly change the information that is downloaded to the Remote Client, create a new download package and make sure to select the option called "APM Remote - Data Collection (Assigned Checksheets Only).
Next update the Mobile Computer in APM selecting the new download package and selecting the Alternative UI Type of Data collector. Choose the one that best suits the device's screen size.
