Not possible to select UTXO in Android version of Electrum! Very bad, I cannot pay anythng because transaction cost is tens of dollars.

Response:
That's unfortunate but there's a workaround.
You can still freeze addresses in Android Electrum so its associated UTXO(s) wont be used in your transaction.

To get there:
Tap menu (3-dots), select "Addresses".
Tap the addresses with the UTXO that you don't want to include then tap "Freeze".
Frozen value will switch from "False" to "True".
Do the same to the other addresses of your choice.

The drawback is if the unwanted and preferred UTXO are tied to the same address, you can't select them individually.

This does not work. Addresses are not UTXO. I have old-format address, so the option "Addresses" show only one entry. However, I have tens of UTXO's on that address, so when I set up payment, it is sourced by many UTXO's and fee is multiplied by number of these UTXO's.

I did not find any way how to select coin or UTXO that will be used for payment.

Hello. I read that AntPool PPLNS pays reward depending on last N difficulty shares, but I cannot find anywhere what N is. Can you please tell me what is (approximate) time duration of "last N difficulty rounds"? Or does anyone know reward calculation formula for AntPool PPLNS?

Hello, anyone else with this problem?
I create backup of my private key, write down the password. Then I go to VERIFY, scan the encrypted private key from PDF document, enter the same password and I get message "The key does not correspond to any bitcoin address".

Tried several times with newly generated backup. What can I do? Thanks, Jan
