Q: Are there different versions of Map Viewer when content is saved? If so, how can we make sure they are 'upgraded'?

I am noticing differences in the settings of Map Viewer depending how you create your Web Map. If you create a brand new map with the Map Viewer in AGOL, the 'Use in ArcGIS Collector' is not there.

When I create a Web Map from ArcGIS Pro (ver 3.2.2) or do a 'Save as' of an existing WebMap in ArcGIS Online, the 'Use in ArcGIS Collector' option is there. I am not using Collector anymore, but this triggered the question why is that option still there when I do a save as? In other platforms (like the ArcMap days) when you do a save as, to brings the product to the latest software version.
Thanks for entertaining the question.
