Just wanted to inform the wallet dev.. I tried to send 25,300,000 dgb using the updated wallet and the amount field glowed red and didn't send. Changed to 20,000,000 and same thing. I was however able to send 12,000,000 and 13,300,000.
Moving onto the exchange withdraw issue. At Poloniex, I attempt to withdraw 29,000,000 and status goes from withdraw pending status to error status. I filled a support ticket and they apologize saying error happens rarely and to now try again. So hours later I'm refunded and try again. Now I have error status again and am filling out another ticket.
Just letting you know because I'm suspecting it may have something to do with dgb send limitations and not the exchange. Is there something that I do not know?
Most likely a more generalized issue. Take a look at this and then let me know if it was a help in at least getting you started down the road to a resolution (and, of course, whatever other trouble shooting results you may also come across).
