Okay - last try, then I’m completely out of ideas...
If you haven’t done so already, go and find Google Maps in Apple App Store - and install it. This is a different App to Google Earth, but in the main has many of the same features.
On your iPad, go to Settings > General > Background App Refresh and ensure that it us turned ON (select WiFi or the default Wifi & Mobile Data as necessary). Next, below the Background App Refresh setting is a list of Apps; find Google Earth and Google Maps - and ensure that their associated toggles are also switched ON.
Now you can compare the imagery for the same area on two seperate Google Apps on your iPad. What you see may, or may not, have differences. Don’t be suprised when you zoom-in or switch the StreetMap level detail if what you see changes - Google’s StreetMap imagery is definitively a different data source - but SteerMap imagery should be the same no matter what App, Application or Web Browser that you use.
Hope this helps you further - if not, and Google themselves remain unresponsive, I’m sure you’ll find a Google User forum that might be able to assist. I wouldn’t be surprised to learn that Google, like Apple, rarely engage directly with the end-user community or the services that they lure you to utilise.
Please remember, to Google, you aren’t the customer - but are a rich source of data and behaviour that can be directly mined for commercially useful information; they watch everything that you do, record every search you make - and if you use Gmail they read your email as well...
