Hey @Katyb. Welcome to the Typeform Community
This is expected because you're needing to pay with a different currency to the one you were on originally when you upgraded. To resolve this we'll need to cancel your plan from my side, but don't worry, no information will be lost. Once this is done we'll be able to make a change and let you know when you can go ahead and upgrade again from your side, this time you'll have the option for the correct currency when you upgrade again.
A couple of notes: Since you're on one of our old plan versions, you would need to upgrade to one of the up to date versions that you can find here. When upgrading you will also need to re-enter your payment method as this will be removed during the process.
If you'd like to go ahead, you can contact the billing team here and request the change. Hope this helps! =)
