Product page optimization: how long does it take to start to see impressions

Hi, my product page optimizations have been approved for 2 days. However, when I check for results today, all treatments are still showing 0 impressions. How long does it take for treatments to start to get impressions?

Same here. Did this test ever start working and providing results?
