Q. I’m trying to send a transaction to my Nano S but it says the amount is invalid?
The Ripple network doesn’t allow an address to have less than 20 XRP. So the first time you’ll send a transaction to your device you must send 20 XRP minimum.
Q. I’m trying to send a transaction from an exchange to my Nano S but it says “invalid address”. What to do?
Some exchanges (such as Bitrex) cannot send transactions on an empty address (the address must be already “activated”, which means it must have already a minimum of 20 XRP).
The solution is to ask a friend to send you first 20 XRP, or to withdraw from Poloniex which doesn’t have this limitation.
Q.Some or all my transactions are not showing. What should I do?
Simultaneously press Ctrl+Shift+A to reset the transaction history. After cleaning, the next synchronization will recover all your transactions.
