It seems that my direct messages are not being sent. How can I fix this?
Anytime you’re temporarily blocked from sending direct messages on Instagram, It lasts for 24 hours.
But you should avoid getting repeatedly temporary blocked as this may put your account at risk. Try to find the reason for getting blocked and fix it as soon as possible.
For example, one of the reasons to get a temporary block from direct messages is sending the same messages multiple times and the fix is to have a wide range of messages defined in your campaigns.
