I started a new G5 sensor this evening on day 94 of my transmitter. Got the circular timer screen for about the first half hour, foliowed by the ??? screen.
I’ve successfully run the transmitters out to close to the max 112 days in the past. Should I assume this one is dead?
It may not be your transmitter. We had that happen to us last week w a new transmitter. The sensor eventually got back in line in time for calibration. So I’d wait it out first.
