Hmm I tested it just now and it seems to work just fine for me

I generated a new keypair and verified that the privkey in my settings tab was the same as the one I input. Then I loaded Astral up in a private browser window and input the privkey and verified that the privkey was correct once more.
Do I need to use damus.io/key/ to convert my keys?
thanks for this. I was wondering why i couldn't use my keys elsewhere
Could be, does your key start with "nsec"? If so, try to convert it. Not sure if Astral supports bech32 encoded keys yet (NIP-19, https://github.com/nostr-protocol/nips/blob/master/19.md)
Astral supports it
