Hi Adrian,
Thank you for your response. Yes, I've made sure the location settings are turned-on for each of the few Android devices on which I've tested the app.
I created the short list based story map on my notebook computer, then opened it on both I-phones and Droids. I've not created any story maps, other than with the short list template, that use a geo-location button. The geo-location button is critical for use of these short list apps I created.
I've not been able to find any info online to help with this problem. This suggests it must not be a common problem, yet I can't figure-out what's wrong.
Greg
