I was told the same, @Thomas, on a recent call to Dexcom. They recommended removing my old sensor and waiting 10 minutes before inserting a new one.
I’m doing a little research for a CGM comparison I’m doing, and I wondered if you guys could tell me what the most common errors are with the G6. I’m very familiar with the Guardian’s errors, and the Libre has very few (one, I think), but I’m still getting to know my Dexcom. I do think waiting that 10 minutes has minimized the amount I’m seeing, but are there common ones that I can expect to run into?
