You may want to take a look at this thread Google Maps no longer displaying (Error - 'Oops! Something went wrong')
It may be missing Google API Key in metadata.xml file.
Hi Sushant & Varathan, thank you very much, from the browser developer console, it seems the Google API key problem, I will find how to put Google API key in metadata.xml.
Hi Sandra, yes it OK to do that to update the key. In fact you can refer to this article guiding you on how to update the key in the metadata.xml API Keys and the Google Map Widget in ThingWorx
Hope this'd help.
