Beacons not detected with estimote app but third party app can see it

I had bought beacons in last year dec, was not using activity but now need to use it.

The estimote app is not able to detect it but third party app able to detect as attached screenshot. any help ?

That’s a bug in the current version (2.25.1) of the Estimote iOS app—a fix is already waiting for an expedited review from Apple, and should soon hit the App Store.
