Unable to use + using Advance Protection – Google Smart Lock Review

After having this app for sometime now, enrolled into Advance Protection and certain sites or apps require using this app for verification. Lately it’s been not recognizing my 2 keys, so I removed my account and tried adding it back, when pairing BT key is sees it I can select it, the final step to enter PIN the entire app disappears. I’ve uninstalled ad reinstalled app and tried many times with same outcome.
