Hello, After upgrading to "5.2.6" the LS caching seems to be not working anymore. A Good example would be : https://www.webpagetest.org/result/180502_B2_0a51048c44a39b6c913552413ba7c557/ Previously the First Byte Time was about 0.6-0.8s but now its about 5s which is totally ridiculous. And when we try to load the pages as guests they load super slow as its shown in the test results. Please note that prior to the update the fully loaded time was around 3-3.5s. I would appreciate any help. PS: upgrading to "5.2.7" did not solve anything. Thank you in advanced.
