Title is self-explanatory. I'm trying to update my game's page (see "Pinori" in my projects) and every time I try to replace an image (e.g. the banner) I get "Upload Failed". I want to be able to update the media on my phone instead but of course, even after requesting desktop website, there's no option to edit the page. I'm tagging this as bug until convinced it's my internet (which is still extremely likely to be the issue). I've had issues with my internet on other sites like YouTube, so it could be my internet, but at least changing my profile picture on YouTube works, so I can in fact upload media. Is there any way I can get the media to upload, like maybe on another device? Things that tend to bug out on my PC work better on devices like my phone, but my phone can't do as many things on itch as it can on PC. Actually, if I get the media to upload through my laptop I'll mark this as resolved/request the topic to close, but if I can't work anything out there's a problem.

TL;DR I can't upload media on my PC because "upload failed" even though my internet is good enough to work. I can upload media on certain sites, but itch doesn't seem to be one of them. Is it a server issue or my internet?
