I have a iphone 11 and updated to the new IOS update this morning. It gave me a warning that it may not work, but it has worked fine for me. Scans and updates my log just like normal. I can't answer about the Libre 3 though. I use a Libre 2. The sensor housing, FreeStyle, Libre and related brand marks are marks of Abbott. Other brand marks are the property of their respective owners.ADC-31522 v8.0 11/23. Get started with the The FreeStyle Libre 2 has the same lower price point as the first FreeStyle Libre system, and can be acquired from pharmacies with a prescription. You will need a new FreeStyle Libre 2 reader and sensors, and the smart phone app (to replace the need for the reader) will be coming soon. First, Abbott needs to update their info; OS 16.5 works with Freestyle Libre 2. Second, my device is also 20+ higher than the OneTouch that I gauge my readings by. But knowing this, it is still useful feedback on foods I eat. The gap did reduce during the 2 week lifespan of the arm unit. Yes, Abbot should adjust for the new OS for accuracy, but On a whim, I pulled out an old iPhone 8 with iOS 15.6.1 on it. It scanned my new sensor and activated it with no problem. I did test the NFC reader on my iPhone 11 and it works with no problems, except for scanning the sensor. Check both your new phone and its OS for compatibility. There is an updated compatibility list (2 days old) for phones To invite someone to see your glucose readings, open your FreeStyle Libre app, ensure you are logged into your LibreView account in the FreeStyle Libre app, then: Open the Navigation Menu. From any screen, tap the “three lines” icon in the upper left corner. Tap Share or Connected Apps. Tap Connect or Manage in LibreLinkUp. After being on the Libre 2 for a year (without issue), I switched the the Libre 3. My first sensor gave me a “sensor not working. Please remove sensor and start a new one.” After wearing for just 3 days. Now, my second sensor has done the same thing after 4. I contacted customer service to replace them, but this is insane. 6ujHZWp.
