My transaction have not gone through for a day. After checking status they were not found but I waited. Gwei was set to fast. Tried sending again but it wasn't allowed. It takes days now or what is the problem?
I have had the same thing happen to me when I accident set a GWEI to low. It eventually went through a few days later. I wonder if the network is jammed up again with the recent Ethereum sell off. If you don't need the funds asap I would chill and periotically check. If it has not confirmed I think you may also be able to cancel it.
