So I am trying to download some large files, but the server I am downloading from are extremely slow. My place doesnt have stable internet connection and during my download, almost 100% of the time, it fails. Now there is a "Try again" button that can continue downloading the file in firefox after the connection is back. When I press the button, it resumes the download from where it was, but I noticed that the files are not downloaded correctly. The file size is noticeably smaller than what it should be, and it is non-functional. My phone uses android 11 custom rom (lineage), but the same issue is also present on an older, stock anroid phone I have. This issue has been present for at least half a year and I dont know a solution. Can anyone suggest a solution?
