Hi, yes I’m suffering the same issue. I have iOS 17.5.1 and my phone won’t connect continuously to the sensor. Been in touch with Abbott, who have sent a whole raft of remedies but none will work. Don’t know where to go next. However Abbott’s compatibility table only goes up to iOS 17.3.1, and I’m pretty sure that my phone worked fine then, so maybe they have some catching up to do.
