Apple MAPS App

Do you have a WiFi+Cellular iPad, or a WiFi Only model?

Only the WiFi+Cellular models of iPad have GNSS/GPS capabilities - this being a function of the iPad Cellular chipset.  WiFi Only models of iPad have no GPS capabilities with which iPad Location Services can derive location. This fundamental difference may significantly impact your ability to use mapping Apps - in particular if real-time positioning (e.g., a moving map) is required.

WiFi Only iPad models can only “infer” their location from a database lookup of neighbouring WiFi networks for which the geographic location is known, or the geographic location of your public IP address. For static applications in urban locations, where the location of IP public IP addresses and WiFi networks are known, an “inferred” location can be relatively accurate. However, in rural locations, or when using a Cellular/Satellite/VPN connection, location accuracy of an inferred location [if it works at all] may be very inaccurate. 

As you have a WiFi Only iPad, as you will only see the inferred location, you won’t see the “uncertainty circle” that you describe.

The circle is a statistical computation based upon the geometry of visible GNSS/GPS satellites - this being known as DOP (Dilution of Precision). This statistic allows a potential uncertainty error to be calculated and displayed. As this statistic is cannot be calculated for an inferred position fix, you’ll not see the the circle.
