@mauricebizzarri @zymbittester - we believe have identified the root issue, which relates to how I2C is managed under Stretch. The problem is more apparent on RPi 3B+, for a variety of reasons.  
Our dev team has a working solution that is being run through production testing and should be available in a new release within 48 hours. Learn more \>

Thanks to you both (and others) for notifiying and helping us identify the root issue.
