Zoom Chat Link - Dropdown menu does not work

Hi,

When we share the following page in Zoom chat, users cannot use the 'Country' dropdown menu to select the country. (Therefore they cannot complete the payment)

But when we email the same link, it works fine (the country dropdown works) and they can complete the payment.

Please let us know the reason for this issue and how to fix the issue.

Regards,
Praveen.
