We are receiving quite a few 400 Bad Request responses from Klaviyo’s API while using `/api/event-bulk-create-jobs`. Although we’re not sharing any phone numbers, the response still states, “The phone number provided either does not exist or is ineligible to receive SMS.” This occurs even when a correct `_kx` parameter or a valid email address is provided.
We are sharing events for business using our software, and there seems to be no way to reach someone on Klaviyo’s team to look into this.
