Ugh, that sounds annoying. Considering what they cost, I’d be taking screen shots and asking for a refund.
Not even just cos of the money, but so that the companies get feedback that their sensors aren’t working properly so that they know they need to improve them.
I mean, for us it’s just an inconvenience, but for people with diabetes and taking insulin, it’s a really serious issue if the sensors are malfunctioning.
