akshaypune , via OnePlus 9 Pro , Oct 1, 2021 : I have a OnePlus 9 Pro (12gb variant) with multiple users enabled. I am using the stock recovery and firmware. I have started facing an issue after the recent update that my fingerprints saved on both user accounts get auto deleted (one or even more fingerprint entries) once or even at times twice a day. It doesn't matter even if the fingerprint is present for both users, it still gets deleted. Is anyone else facing this issue? Could someone help me troubleshoot this? PS: I had taken my phone to the service center, and they asked me to refresh the firmware. I had kept the phone there for an hour and they installed the fresh update, but still facing the same issue.
