Online Basemap Redraw Question

I am using the ESRI "World Street Map" as a basemap. Using Arcmap 10.7.1 on Windows 10. All patches applied to both.

At high magnification  (as far as I can tell a scale less than 1:850) the map does not redraw. More precisely, the basemap redraws but none of the other layers (which are of course above it in the drawing hierarchy) are not displaying at all. When I select a scale >= 1:850 then everything works ok. (The map extents are those of Portland OR).

I don't know whether I would have the same problem at the same magnification were I to choose a  different map with different layers, but the same basemap.

Why is this?

While I am on the subject, when I zoom to a feature what determines the scale of the result? I frequently find it zooms to something like 1:400, but selecting a feature on a different layer can lead to wildly different zoom levels (eg 1:20000 or so).
