Beacons are not detected

I bought beacons that are 200 ( one order 100 beacons at two times) last month(June) but 26 over are not detected by not only my app but also estimote app.
How to fix this problem?

The other 74-or-so show up just fine I assume? If that’s the case, please shoot us a message at and we’ll assist you ASAP.
