[ephixa000]

the home page and search result page is loading fine
but when pressed read, it become very slow only when using wifi (no loading bar, just the circle rotating)(under 20pages is fine)

when i switch to the mobile data, the image will instant load,
instant on/off phone wifi when the mobile data is on, it will also work for the next 40-50 pages, but after this, i have to do the on/off again.

i tried the image load setting, browsing country, image resolution, use original images. none of these help.
