This situation has been quite common recently, especially with newly created BMs and the threshold is still $2. Even though adding cards like Wise or other VCCs is still ok, just creating an ads account or scaling lightly will immediately disable it. It is highly likely that the fingerprint is not clean, the IP is not trusted, or the card has been flagged. You should let the BM rest for a few days after creating, warm up with a light interaction camp with a small budget of about 3-5 days. Combining a residential proxy or 4G and an anti-detect browser will be more stable. If the setup is correct, it will still scale to a normal high threshold, just be patient.
