Dataview and some microflow do not work in sandbox.

Hi, I've created an app that works fine locally. However if I deploy it to the sandbox one specific dataview is not visible and two microflows return the error 'contact system admin'. What could be the cause of this and how do I go about debugging this in the Sandbox environment? Do I need to connect the debugger to this environment? Thanks in advance!

Don't forget to add your data snapshots through the team menu in the modeler.
