i made mistake i guess of making a legacy electrum wallet on my mobile and now i cant pay any reasonable tx fees so i am trying to set up electrum on my PC. is it possible to just open my existing mobile wallet on PC version or do i have to make new wallet on pc and move coins between the 2. thanks in advance
Do you have any bitcoin left on your mobile wallet and do you have seed words backup in safe offline place?
You don't have to create new wallet for PC but you can just import your seed words in desktop Electrum (if you have them) and you will have the option to select all address formats with bc1 bech32 having lowest fees from all of them.
