Experienced this too, think i just refreshed the page and hit the pay button until i eventually got to the btc page.

When you click pay just click once it might not look like you have pressed it but be patient it's so slow you think it's not worked so you press again to make sure that's when you get the message

Hey I had the same issue . What fixed it for me was don’t select country. Just enter address and press pay.I had to press pay a few time and eventually it went to payment page ! Hope that helps

Ended up doing this and it worked! Cheers pal

Same here

Tried all these...STILL NOT WORKING. bring back .org 🙏

My order went through this morning no problem. Guess need a bit of luck😅

Had such issues with every step of the process I wasn't sure if anything had gone through but managed to get on today to check and order has been sent, thank goood

I had this last night. Refresh the page, go to 'orders' and find the 'pay now' button. There is a glitch preventing the payment screen automatically appearing, but the orders are going through and the system is (rightly) preventing you placing the same order multiple times. Everything works - just not a smoothly as it should.

It worked for me by leaving the State part blank, seems pretty hit and miss with all these different methods though.

Any other fixes other than leaving out the country/state? I've tried everything and still getting this error

I removed capital letters and switched to desktop site from android and it went through. Some have said to remove country but i can't see an option for that from country drop down list... Its all fukd! Society keeps saying to enter required fields anx if that's not bad enough Coinbase is being a Fucker too.... Wtf is going on?? So close to Christmas too

I left out shipping option and that sorted it.
was told to correct error which i done then the pay button worked.✌️
