The mempool is not that congested yet, what is the feerate that you used?
5.20 sat/vbyte, i didn't select "mempool" while selecting fee rate, it was set to "static" if it makes any difference
The low priority now is 16 sat, that's according to
https://mempool.space/Maybe increase it to at least 15 sat and it might confirm.
I'm not tech-savvy too, I use electrum as my bitcoin wallet but I always check the site I shared so I would know what fee I would put, sometimes I increase the fee if I need to it confirm faster.
