Estimote demo app doesn't recognize Stickers

I've received some hours ago my estimote stickers! Thank you a lot for the CEO's note inside the package!
Now I'm trying to use the Estimote demo app but I can't recognize my stickers. I've tried the Android version and even the iOS one but neither seem to recognize stickers.
Any ideas?

Thank you in advance

Hi Valentino,

Glad you received Stickers and that you are enjoying. Right now the Estimote app compatible with Stickers is only available via Test Flight, to access it please refer to this link:
