Many advertisers have noticed this issue. The hover function in Ads Manager (which previously showed quick daily stats like ROAS, cost per result, purchases, etc.) seems to have been removed or is currently bugged in the latest Meta Ads Manager update.
What you can do:
- Switch browsers or clear cache: Sometimes it's a rendering bug.
- Use breakdowns (by day): Go to the top right > “Breakdown” > select “By time” > “Day” to simulate daily insights.
- Create a custom report: Use Ads Reporting to rebuild the hover-type summary as a downloadable view.
- Check Meta’s support or changelog: Updates are sometimes documented in their Help Center.
- If you rely heavily on the hover feature for optimization, it’s worth sending feedback to Meta directly via the gear icon > "Give Feedback" in Ads Manager.
