Yes, this kind of performance swing and delivery issue is common after an account gets restricted—even briefly. Here's what likely happened and how to stabilize it:
Account Trust & Learning Reset
When your account got restricted (even for a few hours), Meta likely paused learning and delivery. When reinstated, your campaigns might have lost learning data or performance momentum, causing unpredictable results.
Budget or Delivery System “Cooldown”
After reinstatement, Facebook’s system often re-verifies your ad quality, payment stability, and account signals. This can cause a few days of low or inconsistent delivery, even if ads were working great before.
Shuffled Auction Entry
Meta’s ad auction system is competitive. After a restriction, you may lose your “spot” in the auction temporarily. It takes time to rebuild traction—especially for high-performing creatives like that reel.
Creative Fatigue Over Time
While your reel was initially strong (3–5% CTR is excellent), if it's been running for weeks, it may be entering fatigue or competing with new content in a fluctuating ad auction.
What You Can Do:
Don’t edit or restart ads just yet. Let everything stabilize for 2–3 days without major changes.
Duplicate your best ad sets (especially the reel) into a fresh campaign. This can restart learning cleanly while preserving old data in the original campaign.
Use separate ad sets for static vs. video to let Meta optimize each on its own without mixing signals.
Monitor spend limits, payment method stability, and avoid future funding gaps to keep account reputation intact.
