We've now resolved the incident. Thanks for your patience.
We discovered an issue with the 19.19 release related to the Audit & Inspection module while working Offline in a native app and have issued a fix.
Users working in Offline mode in any of our native apps that have an older offline-synced version of an Audit & Inspection Question Set will see an error when selecting a Question Set in the Audit & Inspection form.
We have resolved the issue, but ACTION IS REQUIRED by users currently synced offline to receive the fix. To resolve the issue, any users working offline must click "Sync Now" from the Offline Sync screen (even if they already performed a sync after updating to 19.19 earlier this morning).
