The location markings can appear incorrectly. If the customer shows his location on camera, on our machinery, but then moves it to another location and, subsequently, back to the original one, the location markings will appear incorrectly. We are talking about the augmented reality features. 

While I recommend the solution, the customer may face difficulties with screen sharing, such as occurs with our customers when it comes to working in an infrastructured area like a factory. We regularly get confused, as we also provide remote technical support. 

The initial setup is complex. 

It's quite power-hungry and some customers complain that it drains the batteries on their smartphones very quickly. This has to do with the remote side of the conversation.
