Schedule tab loads blank page in Trello Power-Up (v0.52.5)

Bug Report

Environment:

• Chronos version: 0.52.5
• Plan: Team
• Browser: Google Chrome (latest)
• Platform: macOS
• Trello Board: Standard board with Chronos Power-Up enabled

Issue

When navigating to Reports → Export → Schedule, the Schedule tab renders a completely blank/white page. No content, no error messages — just an empty iframe.

The Export tab in the same Reports section loads and works perfectly fine, confirming the Power-Up iframe itself is functional.

Steps to Reproduce

1. Open any Trello board with Chronos Power-Up enabled
2. Click the Chronos Power-Up
3. Navigate to Reports
4. Click Export — this loads correctly
5. Click Schedule — blank white page

Troubleshooting Already Attempted

• Hard refresh (Ctrl+Shift+R)
• Cleared all site data for trello.com and chronos.it-pal.net
• Tested in Chrome Incognito mode
• Verified third-party cookies are set to "Allow"
• Confirmed no browser extensions are interfering
• Inspected iframe: loads correctly (1493x715px, visible, proper sandbox attributes)

None of the above resolved the issue. The Export tab works in the same iframe, so this appears to be a server-side or app-side bug specific to the Schedule tab.

Additional Context

I have also emailed it@web-pal.com about this issue along with a separate issue regarding exporting worklogs for former/removed team members. No response received yet on either.`
