I want to get signed up for these mysterious e-mails too. If anyone finds out where to get them, let me know.
I imaged a new cart of iPads yesterday for a new class starting next week. I didn't think about unchecking the upgrade OS, so I got IOS 7 on all 25 of them. Now my Meraki won't load.
On a side note, I notice my older iPads all show in Ft.Wayne Indiana for some reason now on Meraki. We are in Oklahoma, and they were showing in the correct location before. I haven't figured out why yet. This is my first year to experiment with Meraki, at the suggestion of a colleague, and I'm not sure I want to keep trying at this point.
