Are you looping and if so, are you using iOS 13? And if so, did your phone die? There is a bug currently that if you are looping on iOS 13 and your phone dies, your loop and dexcom will lose all settings, including IDs. If these conditions don’t apply to you, then disregard. Just thought I’d pass this along as it’s a known issue in the Looped group.
From Katie DiSimone:
Because someone posts this just about every day like it’s a new thing…let’s leave this here as a proactive message.
Please do not let your phone battery go dead on iOS 13.
There is a really good possibility that you will lose your Loop settings and/or Dexcom app settings (including transmitter ID) if you let the battery run all the way down. If you do run into this, force quit the apps and restart. It may get the settings back, but not 100% guaranteed. Give it a couple tries. Best thing to do though is prevent this situation by not letting battery die.
I still don’t understand how so many people have their batteries die…but apparently many Loopers like to live life on the (battery) edge
