I even tried speeding up the confirmation by doing a "child pays for parent" with a fee of 841/satoshi per byte which is far above the fastest actual fee
according to bitcoinfees.earn.com.
According to them a fee of 571+ sat/byte should give me a processing time of 0-40 minutes, and nothing has happened even after hours
.
That's pretty incredible (and sad at the same time). Just a few days ago I had 80 sat/byte transactions get confirmed in a couple of hours without any issue. But today, I sent a 225 sat/byte transactions and it's still unconfirmed even after 7 hours.
Somehow there are more than 135k unconfirmed transactions right now - which is most likely why is this happening. But still, I don't think your 841 sat/byte transaction should take that long to get confirmed.
