Anyone else have funky things happening with FBA inbound tracking?

Agreed.

As was somewhat-widely reported in the ASF, there have been @ least two separate incidences over the last year or so where Amazon & UPS got their wires crossed, in regards to addresses being presented in the FBA Inbound workflow which were destined for ‘overflow intake’ facilities which UPS had set up in response to staffing issues @ the DCs & FCs.
