Iphone 8 plus does not show in device list

[alphaC]

I have installed prey on 3 devices.

1. windows laptop
2. ipad air 2
3. iphone 8 plus

When I log in to my prey account with a browser, it shows just the first two devices, but at the bottom of the screen it says 2/3 devices.
Otherwise it does not seem to be aware of the iphone.

How should I proceed?

Never mind, I deleted the app from the iphone, then installed it anew. Everything working ok, thank you.
