Warning for a postage stamp transaction when gas price is high

[agazso]

I am trying to buy a postage stamp on goerli with swarm-cli. If I forget to specify the --gas-price option then it will take long time and even if you start a new transaction with a high gas price specified later then still it will wait until the first one is finished.

Maybe it's better addressed in a different layer, but I just wanted to have a record for this issue.
