Meta Ads data no longer syncing in Looker Studio

Hi everyone,
I'm encountering an issue with my Looker Studio dashboard.
Until recently, my Meta Ads data (Meta = Facebook Ads) was properly connected and displayed in my report.
But now, the data has stopped syncing — the fields related to CAC, COS, ROAS, and Amount Spent are empty ("-").

Here are a few details:

  • The Meta Ads connector was already set up and working fine.

  • I did not manually change the connector settings.

  • Shopify data is still syncing properly.

  • I use Looker Studio linked to Shopify and Meta Ads (no Supermetrics or third-party connector).

  • I already tried refreshing the data and clearing my browser cache, but it didn’t solve the problem.

Does anyone know why this might be happening?
Could it be related to a permissions issue, a change in the API, or something else?
And most importantly: what can I do to fix the Meta Ads sync?
Thanks a lot in advance for your help!
