I see the counter of the pending edits, but there are no pending edits in the new review: https://stackoverflow.com/review-beta/suggested-edits says “There are no items for you to review.”
It started happening today (UTC time); yesterday it was fine. The counter redirects me to review-beta/suggested-edits.
On the old review page https://stackoverflow.com/review/suggested-edits the suggestions are visible.
It seems the new page sees the pending edits after the old page, which means the suggested edits are there, but the new page doesn't show them. If I change the URL, and I replace review-beta/suggested-edits with review/suggested-edits, the pending edits are shown, and I can approve, or reject them.
The first time, I have been able to see the pending edits after I kept clicking on the edit counter. I cannot say what caused the suggested edits to finally appear.
