How to fix it?
The first test you did was most probably for a non-optimized version of your page before your site had the chance to serve the optimized content. If you repeat the test after a few minutes, you should see a higher score for the optimized content.
Repeating the test did not help. Now what?
If PageSpeed showed the second test results in less than 1 second, then it has served you cached results. Make sure to wait at least 60 seconds before performing the second test.
I have waited more than 5 minutes before repeating the test, but PageSpeed still shows bad results.
Check if the extension is enabled and if you still have optimizations in your Optimizations Quota. If everything seems okay and you still face the issue, you can contact our support team to identify and fix the root cause.
