We’re using lead cards to get subscriptions to our newsletters. (Note that we’re using MailChimp.) They have worked fine until today.
Now when we publish a card, it’s published as a standard tweet. We have checked the card’s configuration and the data are properly sent.
The weird thing is that the card pined on our profile is still working properly.
Any thought on what the problem can be? (Do you need something specific to check the problem?)
Thank you in advance for your help.
