Hello,
I have implemented the proportional fees request in wallets version 2.4.5 and you can set proportional fees throughout all coinpayments adapters in one setting in the latest adapter version 0.3.1-beta. Also, the 0.5% deposit fee incurred by the platform is now correctly reflected in the transactions table, as is the fixed coinpayments withdrawal fee, which is different for each coin.
0.3.1-beta should also fix the situation where coins were not being listed. Additionally, if there is an error while listing coins, you should be seeing a useful error message in your admin area. Try it in your staging area and let me know.
regards,
Alex
