I recently decided to upgrade computers and sent BTC from my old BTC Core to an Electrum wallet on the new machine. I confirmed the address about seven times, twice with a second person, then hit send. I then went to my new Electrum wallet and put in the amount to be received about 1 minute later. As of 12 hours, I still don't see it in my Electrum wallet, but checking on blockchain, I see that the transaction has been confirmed >60 times. I have the most recent build directly from the Electrum website, running on a Mac. Anyone have any suggestions?
