Experiencing unusual USPS label price adjustments?

[retrogradeco]

When did you get this email? That’s more information than I’ve been given in the 48 hours since this all started. However, it doesn’t address that these adjustments don’t align with USPS policies. As well as the coincidental nature that hundreds, potentially thousands of customers are receiving the same adjustments all of the sudden. My best guess is that there is a serious disconnect in the top-down communication at Shopify. There’s also potential that this is a major USPS glitch that Shopify is having to rectify as the merchant middleman.
