Sandbox dashboard broken - can't create Team Members or manage Shifts/Schedules

Hi, I’m working in the Square Sandbox and running into a blocking issue on two related pages: Team Members and Shifts/Scheduling.

Issue 1: Cannot create a new Team Member
On the new team member creation page, the “Access” step of the new team member flow fails to load with:
“Oh no, something went wrong. It looks like we are experiencing some problems on our end.”
Failed to fetch dynamically imported module: shared-react-mfe-production-c.squarecdn.com/assets/deployed-entrypoint-lYVddMLe.js

This blocks me from creating any new team members in the sandbox.

Issue 2: Cannot access Shifts/Scheduling
On app.squareupsandbox.com/dashboard/shifts/subscribe, the Shifts Plus subscription modal shows the same red banner:
“It looks like we are experiencing some problems on our end.”

I’m unable to subscribe to Shifts Plus or access scheduling features as a result.

Troubleshooting already tried:

  • Hard reload (Ctrl+Shift+R)
  • Cleared browser cache
  • Tested in Incognito mode
  • All three attempts result in the identical error

Status check: Checked Square’s public status page - no active incident is listed for any region.

What I need: I need to create team members and set up shift schedules in this sandbox to test our Labor API and inventory integration. Is this a known sandbox issue, or is there a workaround?

App ID: sq0idp-xsXXvnaq3iP_3-KIaZ-u3Q
Screenshots attached below.

Thanks in advance for any help.

Issue 2:

@irum - This is a known limitation of the Sandbox Dashboard — it does not support the full set of production Dashboard features. Certain UI flows (like the Team Member “Access” step and the Shifts Plus subscription modal) rely on modules that aren’t available in the Sandbox environment, which causes the errors you’re seeing.

As a workaround, you can use the Square APIs directly instead of the Dashboard:

  • Team Members → Use the Team API (CreateTeamMember) via the API Explorer in Sandbox mode to create team members.
  • Shifts/Scheduling → Use the Labor API (CreateScheduledShift) to create and publish shifts. Make sure you’re on API version 2025-05-21 or newer and call PublishScheduledShift after creating — shifts are drafts until published.

Thanks for the quick and clear response, really appreciate the help!
