base map disappears for half my points

[JocelynnJohnson]

Hi,  I have an issue where my base map seems to disappear for half of my points on my map tour. It seems when I have points within one area on my map tour, the base map shows up, but outside another area it shows up as a blank white screen, and vice versa depending on which area I click on first.   I've tried various base maps, extents and zoom levels with no luck, any insight?

This is the first story map I've ever attempted so I'm sure I am missing something extremely obvious, thanks!

Hi,

Sorry about that, this looks like a know issue that will be fixed with next release of ArcGIS Online.
The known issue may happen when a zoom level is used (Settings>Zoom level). If you are using one, using a lower-scale zoom level should resolve your issue (usually it is ok up to level 14 or 15 but it depend on various condition).
If this doesn't fix your issue, please send me a public link to your Map Tour and I will dig more.
