Hi,
I wanted to send all my BTC to one address. The app propted me, that I'm sending to my own address. I did so 4 days ago. The transaction is completed and verified 680 times. But it's "red" and not in my wallet.
If you tap on the transaction and view the details it will show the same as the block explorer, BTC out, BTC in, fee paid etc... so the transaction IS in your wallet...
It just doesn't display as you think it might. Instead of two entries (one entry in the list showing an outgoing amount and one entry showing an incoming amount)... it combines them both into one entry as they are part of the same transaction. It then calculates that the overall effect on your balance was negative (due to the 0.00018356 BTC in fees paid)... so it shows it as "red".
Your total balance (I believe it is on the "Saldo" tab) should show correctly... ie. 0.79508850 BTC (assuming that tx involved ALL your coins)
