Forgive my confusion: Does this mean that for HTML overlays, the content must be hosted somewhere and is loaded remotely, instead of contained in the HTMLResources.zip file and available even when the app is used without an internet connection?Like I say, I may be missing something basic about the workflow.Sorry--brain fart. I was thinking all of the supporting files were in the HTMLResources.zip. Forgot that they just had to be in the folder with the index.html file.
