For two weeks now, approximately from the week of August 10 to 16, 2025, when I create templates with custom values or GHL variables such as {{calendar.name}}, {{contact.id}} or {{paymentLink.Total_Amount}}, Meta has rejected them for the reason: INVALID_FORMAT, this usually doesn't happen with templates that include the contact's name and phone number.
And this is not a mistake with the structure of my messages, since we have tried multiple ways of drafting and structuring, and it's still the same result.
I require you to fix this bug as soon as possible since WhatsApp is the main channel of contact with my leads and I make use of multiple variables in my templates.
