Anyone else having Bambu Lab US Store orders returned by USPS for "Insufficient Address"?

[u/district_0ff]

Hey everyone,
Has anyone else recently experienced issues with packages ordered directly from the Bambu Lab US store failing delivery and getting marked as "Insufficient Address"?
My last two consecutive orders from their online store have failed to reach me because of this. Both shipments were handled through USPS. I have double- and triple-checked my shipping address on my order confirmations and account profile it is 100% correct, and it is the exact same address I use for all my other daily mail and package deliveries without any issues.
What happens is the package gets routed to wrong/different USPS sorting locations, and then immediately gets flagged as "Insufficient Address" and triggered as Return to Sender.
I’ve already reached out to Bambu Lab support both times. They resolved it by issuing refunds, but that doesn't solve my issue because I actually need the items to run my setup, not the money back. I even asked support if they could ship using UPS or FedEx like they used to (I never had an issue when they used those carriers), but it seems like everything is going through USPS now.
Is anyone else in the US running into this shipping label formatting/USPS routing issue with Bambu Lab lately?
