• Report update bugs: "More of a glitch than an issue but seems to happen when updating older reports (~1+ years old)" @9ofalltrades on X.
• Notification and integration gaps: "I'm still having an issue getting notified about internal feedback from review request emails... no response from Bright Local yet" @onyourmarknj on X; echoed in Capterra reviews as "a few rough edges... tools didn't seem to be well-integrated" source.

These point to occasional performance dips in high-volume scenarios, lagging behind the uptime of Ahrefs or Semrush APIs.
