r withdrawals not instant i am non depositor my withdrawal is pending for quiet some time now
AFAIK duckdice process withdrawal instantly. Probably your case is a bit different since you are non depositor player, means that you play with faucet only so probably they need to check your account first and verify that your withdrawal is legit. As long as you did not abuse the faucet by creating multi account or something else which is against the terms then you'll get your withdrawal IMO.
Even older players like myself sometimes gets a withdrawal under review. It's just some security check. I prefer sometimes a manual approval then that some hacker withdraw my funds.
