I got this message yesterday for 3 transactions i have done the tx id did not showed up on blockchain and i only got the message "Rejected because the transaction is not final" how i can avoid such errors in the future because i am worried 1 day the tx will never arrive
The most common reason for this to not happen in the future again is to put more fees on the transaction, the transaction you made probably had no fee, or the fee was very low.
