First Class Option Not Showing Up in USPS upgrade

Hello folks... I'm sure this has been asked and answered... but I just upgraded the USPS module so my USPS shipping rates are correct, and now FIRST CLASS no longer shows up as an option.

Any one encountered and solved this?

Thanks so much...

What is the weight of your item?

Most items are a minimum of one pound. (light going on) Is THAT why first class isn't showing as an option because the item is too heavy for first class? If I set them for less than a pound, will the first class option appear? Next question, how do you enter "ounces" for weight.

Sorry.. newbie here. :D

I believe that 13 ounces is the maximum weight for First Class these days. Please check the USPS web site for details.

Yes, 13 oz is the maximum weight for First Class. Then it jumps to Priority.
Parcel Post also starts at 1 lb I believe. Not sure what is the difference between shipping methods.

16 oz = 1 lb.
You can google an ounces to pounds conversion calculator to make it easy.

Am having the same problem with the same version. Were you able to resolve it? If so, would you mind sharing the solution? Thanks
