Hi,
I have made a video of what i see when the homepage loads.

I have had the page checked on a number of browsers, desktop and laptop. On my Edge browser the cache and all history is removed on closing so I normally use this for testing and all changes can always be seen instantly.
I made the same changes/updates on the staging site but that seems to load normally. I do not understand what is happening, it it was just a cache problem then I would see it load properly on at least some devices.
