@jesika55551 @davidha60766557@jwood_t I have the v350o + OM1. TTL works well for me (although I mostly use it in manual mode). iirc, Micael Widell reported an issue with his first 350o in which it would frequently fail to fire - sounds like a different problem. Did you double check your OM1’s flash settings?
@cfpow@pcdev_assist Sorry I can’t help you with that. I haven’t been responsible for that type of thing since BO3 days many years ago. Have you tried activision support?
