I'm having the same issue. Idk if scam or bug and they just need to rescan DERO wallet but they have not been very helpful in resolving the issue.

Please don't ask them to re-scan their wallet. There is nothing wrong with the blockchain or syncing. They can lose Tx_key and other transfer information if they deleted their wallet cache since the receiver address and the Tx_key are stored on local cache. I am still talking with them to solve the matter.

Can anyone explain why they won't give me the tx private key for my txID (that contains only 2 outputs)?

They may not want to give Tx_Key for the following reason:
1. Transfer to Multiple wallets at the same time uses the same Tx_ID and Tx_Key. However, sharing Tx_Key in this case will not affect other recipient because the recipient address is needed together with Tx_key in order to decode the correct result, and since there is only 2 outputs (minimum) at the transaction, there is no other recipient in this transaction.
2. Multiple Claim. Those holding Tx_key can claim that he's the one who transfer the fund to you. (example: You requested 1,000 LTHN payment from 2 persons. Person#1 transferred you 1,000 LTHN. But since Person#1 posted its Tx_key and Tx_ID publicly, Person#2 can also claim that he transferred 1,000 LTHN to you too). Nobody can prove who is the actual sender as no sender information is stored on the transaction.

For this case, since the receiver only expected from one sender and since they were accused for transferring the coin to wrong wallet, they must come out with the Tx_Key. Or at least provide a screenshot at blockchain explorer with a proof that they transferred it correctly.

For monero-based coin like Lethean, there is another tool called Tx_proof which can solve all the security issues of sharing Tx_key. Tx_proof is generated using Tx_ID + Tx_key + Recipient address, and therefore it's unique for each recipient address. Multiple claim is also not possible since only those with correct Tx_key can keep generating different but valid Tx_proofs for a transaction while false claimer can not.

There is no reason for not sharing Tx_proof for any transaction. I recommend all exchange to provide Tx_proof for their withdrawal process.
