I might have experienced one of these deadly bugs, although I got way to high measurements, not too low.
I bought one of these monitors for fun, because I wanted to see how my blood sugar reacts to different foods. The freestyle libre 3 plus.
After wearing it for some time I woke up one morning to sky high blood sugar, talking 13+mmol/l. My manual measures showed around 4.9mmol/l.
The device was essentially not functioning anymore. I sent the company an email, filed out a report, returned the device and received a new one in the mail.
There is another post here stating a German article saying 'false highs' which is a whole lot more dangerous than false lows. This can cause people to overcorrect and go low. This said, the same CGM should have warned about the low.
As always if your expected blood sugar isn't matching up with measured sugar levels do a finger stick as recommended by the manufacturer. There are a lot of potential device to human interface issues that can happen.
