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.
