@Mayumi I believe somewhere above that @Timothy mentions the current transmitter numbers work as long as you unpair and then pair again. You can always use the method of popping out the same transmitter to restart. Link below.
@ArcherAidan I’ve always used just alcohol, but I had a problem with the Dexcom wanting to fall off within a couple of days. I don’t have that problem with the Libre or my Omnipod. So I use Skin Tac to keep it on and that works great.
