Anyone having big reliability issues with Freestyle Libre 2 Plus sensors?

Hi I have been using Libre 2+ for 2/3 months and have recently moved to Omnipod 5 Closed loop.

I find it consistently reads between 1 - 2 mmol lower than a finger prick. Hence it alarms with supposed lows but in reality I am not. For example libre alarmed at 05.00 this morning saying 3.5 when a finger prick was 7.7.

I am on Omnipod 5 Closed Loop and Libre2+. I have the same problem with low readings 3.2 arrow pointing down during night with alarm going off but finger prick shows 6.6 I ask them to send me a report on failed sensors which I send back but so far no reply

Continuing the Libre 2 Plus issues, has anyone found after the latest LibreLink app update that the event logs don't record much now? I know via other apps that the sensor is not reading any values some times, 1 hour or more. Before the update the event log filled up regularly with Glucose Reading Paused, 373,P events, now it almost appears not to work....
 
The updated Libre app loses contact with the sensor.
I rang Libre, thinking it was the fault of the sensor, and the person I spoke with said it was the app and they’d provide me with a reader.
I was astonished that Libre were using a LibreLink app that wasn’t fit for purpose. Unfortunately I’d already started a new sensor.
Do I sacrifice this current sensor and start a new one with the reader?
 
I've had a problem with my last three 2+ sensors. First one underread lots of the time, second kept losing connection and wouldn't update when scanned. I then took a break. This week I started again. Last night whether lying down or sat up it was reading 3.6 vs 7.1 finger prick, 3.7 vs 6.5 and 3.2 vs 5.8. I've had to turn the low alarm off or I wouldn't get any sleep. Really unsure what to do next.

if consistantly reading lower you could lower your alarm rather than turning it off totally? i set mine lower, however check several times that it is showing at least by somewhat consistant amount and do check via finger pricks after applying new sensors. lowest setting allows is 3.3mmol/L for its alarms.

Report widely differing readings to abbotts taking into account delay, have had a few sensors replaced without issue, i've had to return the faulty ones - prepaid envelope sent with the replacement.
 
I have generally had good performance from mine (I believe), but your query prompted me to check against finger-prick just now - at the higher range (just had breakfast..so a spike) there was only 1% error, but I will check more. I have found that the A1C1 estimate is generally lower than blood tests but my dr explained that it was due to the blood test being 3month average vs the 2week avg from libre. Another factor is that if you lie on your side that you are wearing the sensor it can affect it a lot. I have found that wearing it on the back of my arm vs the side of my arm has improved that a lot (and I also haven't banged/lost any sensors since doing that - before I was losing them now and again catching them on a door frame or when removing clothes...but always replaced by Abbott without an issue when that happened).
