I have recently been running ad campaigns on Google targeting the United States. Surprisingly, a legacy version (v0.6)—which had long since been "Halted" (ceased distribution)—continued to generate new installations originating from Azerbaijan. Furthermore, all ad loads within this version were failing completely. I verified that the aggregated requests and fill rates appeared normal, and there were no ad requests recorded from this specific region. What could be the reason for this?

I’m running Meta ads for a mobile game app (US, Android) and having a serious underdelivery issue. Looking for advice from anyone experienced with Meta/Andromeda.

Structures tested

• CBO: 1 Campaign / 1 Ad Set / 8 Ads
• Also tested 1-1-2 structure

Still unable to spend budget properly.

Problem

• CTR is actually decent (~2.5%–5%)
• CPM looks normal
• But installs are extremely low
• Many days spend barely moves

CPI ranges around $0.5–$1.8, but budget still won’t scale/spend. The plan always performs well on the first two days, but then it basically runs out of steam.

Questions

• For new game accounts in 2026, do you recommend ABO or CBO first?
• If install volume is too low, should I optimize for App Launch or a higher-funnel event first?
• Has anyone experienced decent CTR but terrible delivery/spend?

Any advice would be appreciated.
