What was reported
The fault affected boosts of posts that were already published. Estadao also reported it. The impact was on creating those ads, not on running ads.
Was it a ban?
No. It was a technical fault. Accounts were not disabled for it.
If a boost still fails
Check payment and account status. If both are clear, try again later or create the ad directly in Ads Manager.
