And another question - how many time need for transaction successful broadcast. It`s normal if peer send me getdata after hour then getting inv message

Sorry, sent without RBF

When trying to send a doublespend transaction, it does not accept with error 258: txn-mempool-conflict
How many old transaction can hang in before removal?

The transaction is not accepted by peers when sending, although it is visible in the wallet,
This appeared as unconfirmed 6 hours after sending:

What could be the reason for delaying the appearance / non-acceptance of a transaction by peers
if in the wallet it is displayed normally?
