Likely cause: Timezone mismatch between platforms. If Upstack, Meta, and Google Analytics use different reporting timezones, a conversion at 11 PM EST may appear on different calendar days depending on each platform’s setting. How to reconcile:
  1. Check your Upstack reporting timezone: go to Settings → Workspace and note the timezone.
  2. Check Meta Ads Manager: go to Ad Account Settings and note the timezone.
  3. Check Google Analytics: go to Admin → Property Settings and note the timezone.
  4. Align all platforms to the same timezone for the most accurate comparison. In Upstack, you can change the reporting timezone under Settings → Workspace (this only affects how data is displayed, not how it’s collected).
  5. When comparing, always specify the exact same date range in UTC or use the same local timezone across all tools.
