Hi
I have similar issue with unconfirmed transaction. About 15 days ago, I sent a value to a wallet but after some days it was still unconfirmed. Until now, I increased the fee twice but after this 15 days it shows me still unconfirmed.
2 days ago I sent a small value to the same wallet but with a higher fee and until now, it still shows me unconfirmed.
I´m using Electrum  and atm the position in mempool is 26.92 MB from tip.

Never had issues before, but now it takes too long to be sent.

I appreciate any help.
Thanks

And what is the difference between: ETA, Static and Mempool and which one I should use?
