Can’t connect to beacon in Estimote App on Android

Hi, i have a problem with the connection of beacons with Estimote app on Android, the app show: “Disconneted. Tap to connect”. when i tap the same message shows again, i have a pack of 10 estimote stickers, with none stickers it works.
The stickers are a less 30 cm of the cellphone and doesn’t work.
I attached 2 images of case.

Any suggestion for this.

I’ve got the same problem as you. Did you manage to solve this issue?

When I try to monitor them via Android SDK they are not responding neither. They were working couple weeks ago…
