Changelly is known as one of the scammiest exchanges out there, however in this case it might have been due to the wallet you used that caused an issue. The data you provided indicates that you made the swap from Coinbase Smart Wallet. These “smart" wallets are really just smart contracts and many exchanges can only recognize transactions that come from a normal wallet. I had a similar problem when I tried to do a swap on Sideshift.ai using the Swift smart wallet from Trust Wallet. My transaction was not recognized initially and I had to contact customer service so it could be processed.
