Memepool is really in a mess right now, every crypto transactions carry out doesn't complete up instantly, rather its been delayed because the memepool is congested.
Last night I tried a test using
https://www.viabtc.com/tools/txaccelerator and it worked and today I used it again. Yes, I hope my transaction will be completed quickly with the same fee rate as before, namely fee per vbyte of 40 sats.
