We are currently having KMD wallet issues again on coinexchange.io for withdrawals.
We have contacted jl777 on slack and are awaiting advice on how to fix the withdrawal issue.
Apologies for the delays.
investigating
problem identified, relates to an local error check that isnt taking into account the interests earned, so it rejects the transaction as having insufficient funds.
it would have been accepted by the blockchain as the interests are counted on validation, but I missed a case in the wallet send side.
Will take a bit of time to setup a precise edge case to duplicate this locally, but it is a local wallet transaction creation issue and not a blockchain consensus issue.
Of course, still quite important and annoying. Will work on this today
