There are known issues with the activity logs – including logs not matching the activity log report. This is being actively worked. The fix will be announced in the Change Log sections for Internet Advancement and Scoutbook.
We are sorry for the inconvenience this has caused.
UPDATE: Fixed. Improved the way the roster is retrieved from Scoutbook.com to more closely match it. Remedied “yellow triangle” errors and ensured we are retrieving all advancement/activity information on each Scout - this should also remedy the personalActivitySummary API issue.
