DD's G5 decided to stop functioning some time after we went to sleep last night. For some reason, I didn't get "No Signal" alerts on my iPhone, so I had no clue this had occurred. I was sleeping like a log, probably one of the longest stretches of uninterrupted sleep I've had since DD's diagnosis (with the exception of diabetes camp) and likely would have slept through the entire night had our puppy not started freaking the heck out because my daughter's blood sugar was 380-something (thank you, puberty.) As I mentioned on another post, this puppy, who has never received DAD training, has become an on-again off-again alert dog, despite the fact that we are failing miserably in potty training her. I assumed that DD's sensor had died because it was over 10 days old. So I put in another sensor and clicked in the transmitter and tried to start the new session. No luck; the Share app on DD's iPhone said (if memory serves) "No Signal". I called the helpful folks at Dexcom. The rep had my daughter do a soft-reset on her phone (we don't use her receiver but keep it as a back-up in the event something happens to DD's iPhone) but this didn't help. I'm not sure why he wanted to stop trouble-shooting at this point, but he said that the problem was with the transmitter. As luck would have it, I don't have another transmitter; our cheap-a$$ insurance company sent us only one G5 transmitter and the partially used G4 transmitter that I had been keeping as a backup was already packaged up and awaiting a trip to the Post Office so I could post it to a T1D mom in New Zealand (where the OOP cost for one transmitter exceeds my monthly malpractice insurance payment). I started a slow-motion pre-panic when the rep informed me that he had no idea when they would be able to Fed-Ex us a new transmitter as demand and pre-orders were still exceeding supply. It was then he suggested trying to reload the app but he didn't think it would make a difference, and he said goodbye along with a promise to do his best with getting us a new transmitter some time in the future. Now comes the weird part. My daughter reloaded her Share app and low and effing behold, about 15 minutes later everything's up and running. The even weirder part is that (cue Twilight Zone music and imagine, if you will, Rod Serling narrating the following) "it skipped the 2-hour start-up." Now remember that I had put in a new sensor prior to clipping in the supposedly non-functional transmitter. Recall that even after re-starting a session after day 7 using the "old" sensor, you have to wait for two hours as if you had placed a whole new sensor instead of cheaping-out and trying to wring every possible ounce of life out of the existing sensor like we do. Go figure!
