Several weird problems that led me to do the following.
I had to unistall Meraki on my iPhone. After that I installed it again but when I got to the screen saying "Registration complete! Waiting for your device to check-in" the installation got stuck there. Endless loop.
It's not like I had a choice so I closed this. I presume that cancellation is the reason don't have a Meraki icon on my iPhone. But the thing is that when I look at the Meraki dashboard on my PC I can see my name as a registered user for Meraki.
The real sad thing here is that I can't complete the Meraki configuration on ny iPhone because I don't have a Meraki icon.
I hope I gave you enough informations so you can help me get through that installation.
