Home App and Yale Lever Lock

I recently installed a Yale Lever lock, which is compatible with HomeKit,. For the first couple weeks, it worked fine. Recently, when I try to lock or unlock the device from the Home app, it says "No Response". A few facts to keep in mind:

• I checked the lock's batteries - they are all full
• The lock is responsive when using the Yale app
• The status of the device within the Home app updates right away (i.e. Locked, Unlocked) whenever I take an action from the Yale app or manually locking/unlocking the lock - so I know HomeKit is communicating with the device
• My other devices are still responding normally from the Home app
• I tried restarting my phone, no change

Any thoughts? Thank you.
