RAK2171 Factory Reset?

LPWAN Nodes
1

Is there a way to put the tracker in factory mode?
What happened is that I added it to the TrackIt app, then I removed it from the app.
Now every time I try to pair it again it says it’s already registered to another device.

Ideas on how to proceed?
Thanks

BUMP! I too would like to know how to factory reset these if necessary. When was the last firmware update? Very little documentation available.
