Is it possible to get the live version of OpenStreetMap as the basemap for my ArcGIS maps? Until about July 1, 2019, I could get the live version of OSM as my background map, and see the updates to OSM that I had done minutes before.

Until 2019-7-1, I could use ArcGIS to produce trail reports.  First, I would put my updates onto OSM with the Java OSM editor, then I would produce an annotated map with GIS showing location numbers where pictures were taken.  The OSM basemap now available with ArcGIS is not the live version available at www.openstreetmap.org .

We did switch to use the Esri-produced vector format basemap at the end of June (close to the time frame you noticed the change).  This basemap is now one of the default options in the pull-down gallery

1) if you are an anonymous user (i.e. not logged in ArcGIS.com) and

2) if you are part of a new organization that joined ArcGIS.com after the end of June. 

Your organization administrator can still display the default raster basemap gallery which includes this OSM-hosted raster version of OpenStreetMap.  Or you can build a custom basemap gallery that includes a combination of raster and vector basemaps.
