Hi Rod. This is a really great module, and has been working hassle free for me for a good 12 months now. However, in the last few weeks I have noticed my customers have been overcharged for postage on letter/large letter size products. It no longer charges the letter rate and jumps straight to parcel. I can assure you I have letter enabled and the products are the right weights and dimensions as it was working in the past. Would this be due to an external problem? Can anybody else test and let me know if they're experiencing the same thing?
Thanks!
