Freestyle Libre 2 Reader - Does it work?

I can confirm that the alarm on *my* reader does not seem to be working. I set the low glucose alarm to 5.5
My readings across the last two hours were 7.0, 6.7, 4.9. No alarm :/ I'm not hypo, so not confused, and the reader is sitting right next to me on my desk. Something seems to be wrong. Googling the manual

Edit: this is the first time I've used the reader and not my android so I might be doing something wrong. I stopped using the android app for this sensor because Abbot sent me an email saying that alarms were not working properly with Android 13 which I updated to last week. But 4.9 should have set off the alarm on my reader so maybe it's a more widespread problem???? I don't mind during the day because I check fairly constantly but my usual 3AM low does worry me. Maybe I'll just set a different alarm to wake me up at 3AM to check

Read the 'instruction' leaflet ? ( you won't get another alarm UNLESS the reading doesn't go above set alarm )
Set my low for 4.0 as this gives me time to do something about bs getting any lower

I've now read the instruction leaflets from several countries. They're all different despite having the same behaviour as far as I can tell. E.g. not related, but the Australian leaflet says you cannot put a breathable patch over the sensor, the Canadian version says you can as long as you put it on at the same time of the sensor. Which to believe?
 
You have to start a new sensor with the reader not the app in order to get the alarms then start the sensor with the app to get readings- - It's a mine field ! ... also , if you're using Libreview you will have upload the data from the reader.. Good luck , it's really not hard to do
Think I'll be looking into changing to Dexcom - Your thoughts ?
 
Yes you can wear a cover over sensor whether using app or reader (I have but don't use)
 
My thoughts are that Abbot sent me an email saying that alarms were not working with Android 14 and to use the reader until a fix was ready. So I started the sensor with the reader, not my phone, because I recently updated to Android 14. The alarm did not go off from the reader, which the sensor is paired with.

The Australian instruction leaflet says that you cannot. The Canadian leaflet says that you can. This is my point
 
Oh dear - I don't know what to suggest- In my mind all should work so long as you've 'paired the sensor first with the reader. Have you checked settings are correct and om ? Speak with Abbott if you're not able to solve the issue with others 'answers'
P.S. Let us know the outcome..

Oops, Android 13 not 14. But the sensor is paired with my reader not my phone this time. I am saying that I did not get an alarm this afternoon from my reader when it dropped below the threshold and I was previously well above it.

Only look at what country is relevant to you !
I got caught up looking at Unied States not United Kingdom
I get your point
 
Yes I have always used a patch and now another company comes with a hard plastic cover that goes over the sensor and held in place with the patch all of wich worked fine until the last 10 or so sensors, I do notice that it loses signal complety when I lay on that side on a memory foam matress wich makes sense to me. Is it possible that is what happen?
