I have two transactions currently stuck in the network, one going into an Electrum wallet and one going out. I sent bitcoin from that wallet using a 75sats/byte fee about a half hour ago, and it's still sitting there.
OP, this has nothing to do with Electrum and I don't know if you're aware of that or not. The network has been pretty congested for at least a few days now.
You will have to wait a little bit more for a confirmation or try using RBF (Replace By Fee) or CPFP (Child Pays For Parents, if you are sending the transaction to an address you own) in your transactions (basically, pay more fees to try making it confirm faster).
Yep, good advice. It's weird, we usually see bitcoin acceleration services popping up at times like this but I haven't seen any lately. I know lots of them are scams, but last time it was really bad there was at least one miner who was helping people out (IIRC).
