Dear ShippyPro,
as far I understood in your UPS implementation there is a limitation of 35 chars for the concatenation of address1 + address2.
I have talk to UPS and this limiation seems to be on the shippyPro side as in the UPS interface you can send an array of max 3 positions with every position with a max of 35 chars.
This limitation on your side you causing a lot of issues with one of our biggest customer.
Hope that you can review this ASAP
