Invalid zipcode message when trying to create shipping profile...

I keep getting this massage but only on the app, however, I've tried making changes from my laptop and they work on it but have no effect on the app which is what I use primarily. I've tried multiple zipcodes and every single one is invalid. This keeps me from being able to complete any new listings and is costing me money that I need to be making. This is day 3 and to say I'm frustrated would be a huge understatement. I've worked very hard on my inventory and setting my shop up but this makes me want to leave it all together.

You need to enter your own zip code

I saw where another post found you now need 3 things, that have to be done through a browser, not on the app

ship-from country
zip code (postcode) that is valid in that country
AND number of days to deliver (not just processing times)

otherwise you get that message

and once it's updated, you can list through the app.
