Ever since I updated to iOS7, YouTube videos do not show up in forum threads in various forums I frequent anymore. There is a big black blank space where I can tell there "should" be a video visible but nothing to click on. VERY ANNOYING!!! If I clear my cache, it may display one video when I click on a known thread with a video in it but after that, the rest of the threads that have videos will be blank!! Any help would be appreciated.
