Account limited or blocked by Meta

Why

Meta watches message quality: when many people block the number or report its messages, Meta lowers its rating, reduces how many people it can reach, then may block it. A message against WhatsApp's rules has the same effect.

What to do

Open WhatsApp Manager: Meta explains the reason there and, when possible, offers to request a review.

Only message people who agreed to hear from you, say clearly who you are, and give a simple way to stop. The rating recovers over time.

Only Meta can lift a limit: neither Nodium nor the software that connected you can.
