1 sat/B is probably not enough for the TX to be confirmed within 5 blocks.
As you can see on the site above, the amount of TX (and therefore also the needed fee rate to get confirmed within X blocks) has gone up a few blocks ago.
This may clean up soon. I do think your TX will still confirm today, but maybe not within the next 5 blocks.
But since this isn't urgent, i guess you are fine.
If you somehow still need to bump the TX, you might also use CPFP to do so.
It looks like the mempool increase in size significantly just after I have submitted my transaction. Seems like bad timing from my end
Will wait for it to be done, no need to bump it
