I’m not 100% sure, but that seems to be an Ignition thing rather than an Opto thing. (We just put their vanilla Ignition app on EPIC/RIO, we don’t make any changes or additions and for sure we don’t mess with their certificates).
Can you also post this on their forums… I think you might have a quicker / better response there.
All that said, I will double check with the team tomorrow (Monday morning our time).
