TIKTOK ADS

Job ID: 30959632

Budget: $10 – $30 USD

I specify a budget in Tiktok.
Example $100 and I want it to run for 24 hours.
But when it reaches 20 hours, it no longer fills the budget and spends no more money.

"Ad group out of budget"
I am getting this warning.


Even if it fills the budget, what can I do to spend extra?
Please I need specific and clear answer with knowledge on the subject.
