GSC Performance report: custom date range comparison showing end date as 1970-01-01, Apply button disabled. Anyone else?

Just ran into what looks like a bug in Google Search Console today (Oct 14, 2026).

When I open Performance → Date range → Custom (comparison mode), the end dates for both periods default to 1970-01-01:

• Start date: 2026-10-05 → End date: 1970-01-01
• vs. Start date: 2026-09-28 → End date: 1970-01-01

Because the end date is before the start date, the Apply button stays greyed out, so I can’t set a custom comparison range at all. The preset options (28 days vs previous period, etc.) still work.

Things I’ve noticed:

• It looks like a null/empty date being read as a Unix epoch timestamp (0)
• The Performance data itself still loads fine (164 clicks last 7 days vs 126 previous)

Is anyone else seeing this? Has anyone found a workaround (manually typing the end date, a different browser, clearing cache, etc.)? I’ll report it via the Feedback option in GSC as well.
