I decided to try lingo because I’m currently on Zepbound for weight loss and occasionally think I have blood sugar drops. I applied it and everything was well. First reading after the hour was low but then it quickly jumped up to 74 and I checked with a finger stick that read at 81 and I felt good about that difference. Went to bed and slept on my opposite arm. Overnight my readings looks funky. Very very low. Then it was saying sensor error. Decided to take my sugar as a finger stick to compare. Last readings were under 55 and 57 around 7. I took a finger stick at 750. No possible way it jumped like that on its own. Should I contact customer service for a new one? Or should I ask for a refund and just use finger sticks as necessary
