Native or Canonical bridging can take up to 7 days with withdrawal from an layer 2 or layer 3 chain back to the origin chain. This wait time is set by the chains themselves and not something we at Relay can control.
The 7 day period will start with the prove withdrawal transaction is completed on the blockchain. Our transaction page for your bridge will reveal that prove withdrawal transaction; you can look your bridge up here: https://www.relay.link/transactions/
The 7 day wait period starts after this transaction is completed. You will receive your funds a little over 7 days after your prove withdrawal is confirmed. You will receive your funds around this time & if you don't, please reach out so that we can insure that you do.
