Expedited USA dimensions not working?

[xtremetech99]

Some reason today when i try to use paypal canada post shipping tool it wont let me use expedited USA parcel. Says Not valid dimensions..   my size is 9x6x4 INCH  4LB   . I tried a bunch of different sizes but still not. I have used this method many of times before with the same size.

Since the price of Expedited went up I am trying to look at the cost of Tracked Packet but I keep getting the above error. I have tried the tricks mentioned to get it to work, but it never did. 

Once you get that message for TP click on overview to get out of that transaction, then go back into it. That seems to work for me.

I have the same problem regularly (for the last year+).  I am noting a distinct pattern though,  it seems that when a buyer purchases two items, and ebay groups the items together in one package for shipping,  this "invalid dimensions" problem occurs.  A real pain in the neck!!!
