@mattbrown015

if the end device ignores about 5 or so downlinks they change to SF12BW125

I think that only applies to ADR? Then, yes, courtesy of TTN:

@arjanvanb

TTN deployed a fix to send commands on SF12 if a node is erroneously expecting RX2 to use the LoRaWAN default SF12 rather than the TTN EU868 SF9, and is not responding to the SF9 ADR command.
