A Microsoft file hosting and synchronization service.
I had the same problem - I did THIS and it worked (finally)
- Signed out of One Drive on BOTH old and new android devices
- Uninstalled OneDrive on BOTH devices
- Turned off VPN on BOTH devices
- Re-installed One Drive on OLD device and Logged back in
- Completed Personal Vault set up on OLD device (successfully) and picked new 6 digit PIN in the process
- Re-Installed OneDrive on New Device
- Logged into OneDrive on New Device
- Completed Personal Vault setup on New device, using SAME 6 digit PIN as old device.
- Personal Vault setup on New device Completed Successfully
I am very curious if this works for anyone else.
