I've shared a folder that was about 337 MB using a share link. The downloads are abysmally slow at 47.83 KB/s to 185.54 KB/s. Then the download fails at less than a third of the way through.

I'm on a paid plan. Replicated with the person whom I shared the folder. Both of us can't download it.

Both of us are on different high bandwidth fiber internet plans and have no issues with other content.
