1. Private account
The most common reason. Keep it public until the order completes.
2. Wrong link type
Post link for likes, profile link for followers. Mixing them up stalls the order.
3. Duplicate orders
Two orders on the same link at the same time confuse start counts. Wait for one to finish.
4. Flag for review
On Instagram, turn it off before ordering followers.
5. Changed username
If you rename the account mid-order, delivery stops.
6. Platform updates
Sometimes Instagram or YouTube changes something and suppliers slow down for a day or two.
What SMMJet does
If an order can't complete, it's marked Partial or Cancelled and the undelivered amount returns to your wallet automatically.
