The ability to upload worlds work, its just that there is a problem with uploading my 500mb world. I can assume from the problem with downloading worlds that are over 100mb emerged mid June, we now must face the problem with uploading worlds that are over 100mb. My attempts of uploading my world the old fashioned way of using file.io obviously didn't work because it was also the reason people couldn't download their worlds over 100mb, so I decided to use the Minehuts "upload world" feature instead, and sadly, this didn't work either. I hope in the future this problem can be fixed as well, because I am currently in a situation regarding failure to upload my world that's over 500mb.
Thanks,
