I sent three transactions from my Electrum wallet yesterday. I used Electrum's dynamic fee slider to pick the fee. I pushed the slider one above the middle to increase the fee slightly in the hope it would speed things along (although I noted that however far up the slider I pushed it it always estimated confirmation within 25 blocks).
The first transaction was over 22 hours ago and it still hasn't had a single confirmation.
Looking into it a bit further, for example using BlockCypher, I see the fee is considered low. But still... 22+ hours?
Here are the three transactions on BlockCypher.

Most worryingly, Electrum is showing the third transaction as "Unconfirmed Parent". I also note that on the BlockCypher page for that transaction it only has a confidence of 61.55% and says "Double-Spend Detected: No Memory Pools With Tx: 974"
The three transactions should empty my Electrum wallet. When I did the third transaction, I used the "Max" button in Electrum (after setting the fee) to send all that was left in the wallet. Has Electrum used some of the funds used in one of the other transactions in this third transaction? Is that why BlockCypher thinks it has noticed a double spend?
I'm rather worried that these funds are all currently stuck in limbo!
Thanks in advance for any info you're able to provide.
Just wait for a few hours, I sent all my btc from electrum to coinbase, it took me almost a day before the confirmation. I think they are working on to something that's why there's a little delay on bitcoin transactions. Just hang in there.
