Local send works well for me between android and iDevices in most cases. I will say it struggles with VPN’ed connections, which is by design of the network and some VPN will block local connections.
I know sharedrop.io uses a similar web based model as pairdrop and runs into the same VPN issue, but I’m curious if the room function might overcome that in pairdrop.
This is a decent video explaining some of the background on why polling got worse from business insider. Essentially it has more to do with conservatives being underreported (they don’t like talking to pollsters) then Gen Z, Millennials, or Gen Xs. Not saying that didn’t play a part, but Nate Silver has talked about this as well in his Silver Bulletin.
