Motiv Mix Keeps Disconnecting and Reconnecting in Device Manager

I recently purchased a Shure MV7+ to replace an older broken MV7. My understanding is the only way to adjust microphone sensitivity on the + version is to use the app. (The older mic had an adjustable sensitivity slider on its body).

After installing Motiv Mix, I hear a beeping sound every 2 seconds. Closing the app makes it go away, and re-opening the app causes it to start again.

It sounded like the "new device found" alert sound, so I opened the device manager and I see the list of devices keeps refreshing, in time with the beeps. I've uninstalled and reinstalled the app, then tried manually uninstalling Motiv from the device manager and rebooting, to no avail.

Lastly, I tried uninstalling Motiv Mix and installing the older ShurePlus Motiv app -- unfortunately that app is not recognizing the mic at all.

Has anyone else run into this? Any recommendations?

Thanks.
