I am not sure why, but other countries keep emailing saying they can’t check out with their country. When I check my website, it only shows United States and it greyed out, so you cannot choose another option, I do not understand why though, please someone can you help?
If anyone is reading this and experiencing the same problem, we found the solution on another thread:) Wanted to share here: Just go to settings - then Markets - from there you can activate the other (international) markets. Check back on your store and you should now see the ability to choose other countries, just as we did! Great resource and community here on Shopify, jusy paying it forward, hope this helps you and may you receive much success on your journey.
