G7 sensor fails to link up

I experienced a brand new problem today. I inserted a new sensor with correct code and paired it up. Took longer than usual Which seemed strange but it did so eventually. Put correct code into pump.
The app was working after warm up but the warning red sign came up on my pump as no connection( which is usually when the pump is too far from the sensor). This went on for an hour so the problem was not the usual one.
Dexcom said it was not their problem as the app was working, but a pump problem.
Contacted Airliquide agent. She identified the problem as resulting from the old, defunct, sensor being too near the new one, confusing the pump. The answer was to reset the pump, insert a new cartridge and lo and behold all was well.
My point is that I never received or have read any warnings about making sure the old sensor is removed 20 metres away from the new one! ( which was her advice).
In 21 months I have obviously been lucky that this has not happened before as the sensor has always been replaced in the same place, same procedure.
Although I called customer support, I think I could have fixed this problem myself had I known the cause and solution.Others might find this helpful. I have looked at other forums but cannot find any warnings about this elsewhere.
 
Hi Judith
Ive just had the same problem, I called the pump helpline as I find them more helpful than dexcom to speak too, they talked me through the same routine and also mentioned it might be because I was still wearing the old sensor ( although mine was the other side of my body ) I always start a new one on my phone first as I need 12 hrs to 'bed in' and give accurate readings that im happy to have closed loop work with, but to be fair this time I didn't remove the old one straight away so will make more effort in the future.
It is good that you thought to let others know, as you say it is not something we have been warned about.
 
Go to bluetooth and delete all previous G7 connections, you'll find there's many on your phone, I think this causes a disruption with new connections, I had the same issue and did the same and it connected fine afterwards.
