Hello @brad . I encountered exactly the same problem as here(Trained model runs with error on mobile with Lens Studio), when not a single model from Roboflow runs on the phone. Have you heard feedback from Snap? Over a month has passed, but no positive changes have occurred 
Unfortunately I did not (and don’t expect to given their lack of engagement recently). Supporting custom models & integrations doesn’t seem to be a priority on their end and their system is a black box from our end 
Thanks for the quick response!
It’s sad that such an interesting functionality was abandoned. I hope the situation will improve soon
