As you said, it only has two probability. First, because of your browser problem. Second, because of you hosting provider delaying problem. In my opinion, it's because of your browser problem. Many hosting provider out there claim that they provide the best service as their can. These including free hosting provider. I have taken survey on 4-5 hosting provider especially free hosting provider and so far they all provide a real time update when you uploading all your work file. I am using Chrome, has setup a website 2 years ago on one of the free hosting provider. So far, I haven't encountered any problem yet. My recommendation is, have a fresh installation for your browser if emptying browser's cache seems don't work or all of other method you try doesn't work. Regards, QilleRz.
