It's been a day since I posted my new pfp and it still hasn't changed on my profile yet. Normally it would've updated by now.

To elaborate on ^ that post, your Browser is caching the old image so it doesn’t look like it’s updated. Ctrl + F5 refreshes the cache and lets your Browser show you the updated picture.

From what ive found (didnt test it myself yet) it should be possible by typing in "javascript:location.reload(true)" in the URL, also works on Desktop PCs. The only other way ive found is to manually clear cache on all sites in the settings.

Ctrl+F5 did the trick, but it's a little dumb that that is necessary.

If you want the site to never cache anything on your hardware you can set that in your browser settings. 

If it's a little dumb, you won't mind a little extra time to load each page and a little extra data used.
