It can be pretty frustrating sometimes trying to track what is happening when transferring a domain. I recently transferred a domain to DH that never did show up in the “pending” list on the DreamHost panel even though the transfer did actually go through.
As long as you have done all the right things (unlocked the domain, entered any required auth code, etc.) sometimes you just have to be patient. ICANN rules allow up to 5 days for a registrant to object to a transfer request - so it often (usually?) does take that long.
Some losing registrars give you a way to “authorize” the transfer, while others just wait the 5 days and then complete the transfer if no objection is received.
