We have been on 2025 r1 for months without any issues. Today we are unable to generate USPS Priority labels, we receive a popup error, This file already exists. We can generate USPS Ground and Fedex labels without issue.
We are using the easypost connector, if i login to the site i can generate labels without any issues.
I already tried setting up a new carrier in Acumatica and mapping the shipvia to that carrier, same error.
Any ideas?
