FWIW: My recent experiences with International mail is this: since Covid, it has become common for item tracking to fail between countries. eg: I get notification the package has departed and usually no further tracking until delivery. This has been my experiences in BOTH directions, packages from the US, UK, Argentina, Germany, Italy, France but - they all arrive. On the upside however - the best tracking I have is via parcelsapp.com - even though my local Postal Service is tracking I get more updates and better information via parcelsapp - hope this helps some of you. 61 days I waited for a parcel from San Francisco - about the same time it took a package to arrive in Germany - mostly because there are far fewer planes in the air because of Covid. We just gotta' be patient and hope Covid is dealt with and soon.
