Facebook Ads “Token Error” Connection Failure

Most Facebook Ads sources have now fully recovered. A very small number of sources in the US remain affected, which can be resolved by reconnecting the credentials. No customers outside the US are impacted.

The incident appears to have originated from an interruption on Meta’s side, which likely triggered false token/login errors and temporarily blocked sources from running in Funnel. While Meta has not confirmed details, the timing strongly suggests a link to their earlier service disruption.

We continue to monitor closely and support customers still experiencing issues.

Since 14 August 2025, we have seen some Facebook Ads data sources fail with the error “You cannot access the app till you log in to www.facebook.com and follow the instructions given”. This issue stems from a change on Meta’s side that requires certain accounts to re-login, even when tokens remain valid. As a result, affected sources stop importing data.

We are doing all we can to mitigate the impact for our customers and are proactively addressing the issue caused by Meta’s change. Our engineering team is bulk-triggering download jobs for all affected sources to restore imports, staggering these runs to avoid exceeding Meta’s API limits.

Backfills are temporarily paused to prioritise ongoing data imports. Around 20% of sources have been processed so far, and we will continue until all are complete.
