2.70 - Unable to lower volume using headphone controls

Using JBL Reflect Mini 2 - before the 2.70 update I was able to control the music volume just fine, but after updating the watch only responds to the "volume up" function. Paired the headphones with my phone and both up/down is working so it's not an issue there. Tried unpairing/pairing them with the 245M again, power cycling - no go. Anyone else having this issue?
