Sorry to hear you’re experiencing issues when trying to enter your card details and select a plan. Rest assured, I’ll do my best to help rectify the problem.
This may be due to a browser / local issue on your end. Could you try follow the troubleshooting steps listed below and then re-entering your card details to proceed with choosing a plan?
Try a different web browser, as well as incognito or private windows to rule out any browser issues.
When using incognito, if you are still experiencing a display issue, confirm you have disabled browser extensions as these can change how the pages look.
Ensure the web browser is up to date on the latest version (we don’t support every browser, but we do support these ones)
Try another device, like another computer or mobile phone.
Try another internet connection (switching to a cellular network on a phone rather than wifi, for example)
Ensure you do not have any firewalls or pop up blockers enabled on the device as these can interfere.
