Ive installed the gui 3.2.2, is fully synced and working properly
you try to send XHV?
I'm usually mining XHV and holding on the wallet, but just for this curiosity I've just sent 1 XHV to my Bittrex account and the TX passed regularly
Why? you have problems?
If nobody else has issues or is reporting any problems, that should not be happening to any transaction.
