After 2 weeks, the purged of transactions worked perfectly.

I did a transaction of 50 nested segwit utxo to one native segwit address with a low fee.

I considered a low fee, because transactions are measued by kb size and the fee was really high over the value of the transaction.

However, it did not entered in any block in 2 weeks, time when the network make a purge and your transaction is forgotten.

However, I wonder why it didn't entered in any block in 2 weeks if non of this blocks were full. The 10 minutes time per block limit this kind of transactions and keep the sat/vB high.

I will try again with a higher fee, 3-4 sat/vB.
