Thanks for the feedback - a public or accessible bug list would be very helpful with this sort of thing as we’re just discovering the already discovered.
I think there could be an issue with some mangOH yellow boards regarding airplane mode which has highlighted Octaves inability to handle this edge use case. We have eliminated the mangOH power source as the cause.
The problem is we are also experiencing the unrelated network registration issue at the same time which was making diag really difficult. I’m hoping the network registration workaround should help us focus purely on the airplane mode issue from now on
