Describe the bug

1990s: all web software correctly resumes downloads.
2020s: all modern web software fails to resume downloads :)

After the download fails (which is very often), and "resume" is clicked, next click on "install" always restarts the download from 0%.

Deepseek maintains that this line:

FileOutputStream(target, true).use { output ->

It could be onto something, idk...

To Reproduce

Get your download to fail and resume.

Expected behavior

Resume should work. And it should work on its own, without a kickstart.

• Devices: Samsung M51, OnePlus Ace3
