Your plugin worked great to download all the different tax codes by zip code for MN. However, now with 1,023 lines in the Standard Tax page and no priority automatically entered (that would have a nice touch), the wordpress standard tax rate page loads but won't let me change anything. I should say it will let me slowly add a priority, one by one, but it takes literally 5 minutes for WordPress to allow a new click. Too much data!
So, unless there is a way to upload all the priorities to 1, I either have to manually enter all of them or delete the tax rates row by row (another 5 minutes each click). Surely I'm not the only one with this dilemma?
