Quidel Quickvue Inline Strep A control line issues

Hello all! We have had a couple dozen POCT testing sites report issues with our Quidel Quickvue Inline Strep A kits, particularly lot number 708811 (with a 12/29/24 expiration date). We are seeing splotchy invalid control lines for almost every patient test. Our QC positive and negative are just fine; we're only seeing it on patients. We've already followed up with Quidel and opened cases, but they are doing their usual troubleshooting, which takes some time, and it doesn't seem that any other organizations have reported issues at this point. Does anyone else happen to use this kit, and if so, are you experiencing any issues? Thanks!
