Hi @dang not sure why but when I click Share -> Copy Link in the Reddit iPhone app, and submit the url to HN, the URL seems to get messed up (this submission is a good example). I tested the URL before submitting to be absolutely sure it worked, and can confirm it did.

This is the original URL submitted: https://www.reddit.com/r/SpaceXLounge/s/HSdpFU7CD4
