I have a similar problem trying to download to /tmp/<temporary directory>.
Snap seems to remap it to /tmp/snap.chromium/tmp/<temporary directory>. Chromedriver is allow to write to it, and the download actually works.
The problem is that /tmp/snap.chromium have 700 as permission, so only root can access the file.
