Summary
- Dynamics 365 Commerce Store Commerce operations are failing after recent browser/runtime updates, with errors converting date values to Edm.DateTimeOffset.
- Reported impact includes cart line updates, customer creation, and potentially any workflow that processes affected date values.
- The issue appears tied to historical time-zone-offset handling in Store Commerce and how requests are formatted before reaching Commerce Scale Unit.
- If you are affected, Microsoft suggests two mitigations: change impacted devices to UTC time zone, or evaluate a temporary rollback of the exact working WebView2 Runtime / Edge / Chrome version with Microsoft Support.
- No action is required if your environment is not experiencing the issue.

Microsoft Message
We are investigating reports of failures in Dynamics 365 Commerce Store Commerce operations following recent browser or runtime updates. Affected operations may fail with an error indicating that a date value cannot be converted to Edm.DateTimeOffset.
How does this affect me?
Reports include failures when updating cart lines and creating customers. Other operations that process affected date values may also result in failures. Our initial investigation indicates that changes in historical time-zone-offset handling can interact with Store Commerce’s date formatting, causing certain requests to contain date values that Commerce Scale Unit cannot accept.
What action do I need to take?
If you are impacted by this issue, please review the available mitigation options listed below:
- UTC time zone: Please change impacted device’s time zone to UTC to avoid the failures. Validate the affected workflow and the impact on local-time displays, timestamps, scheduled activities, and integrations before broader deployment. Please ensure that you are changing the time zone and not the system clock.
- Temporary version rollback: A rollback to an exact, previously working version may be evaluated with Microsoft Support. For the Windows app, this concerns the WebView2 Runtime; for web-based POS, it concerns the Edge or Chrome browser. These require different procedures. Rolling back Edge alone does not roll back WebView2.
This message is for awareness, and no action is required if you are not currently experiencing impact.
