I had an issue yesterday with delivery of my replacement power bank, which is being sent back to the sender. Anker will be sending another power bank out, this time to a second address which happens to be a house vs my apartment. Hopefully I receive it this time. They used the carrier Swiship which I never had an issue with in the past. My CGM sensors are delivered through them and they have been pretty accurate in delivery in the past 9 months.
