One Drive Personal Vault Lock Notification

Hi,

How do you turn on the Windows 11 - One Drive - Personal Vault - "Keep Personal Vault open" notification? May not have worded it exactly right but that is the essence of the question.

Am on Windows 11 (personal), open One Drive, click on Personal Vault, unlock Personal Vault, Personal Vault file explorer page opens. So far no problems - works as expected.

Setting for Personal Vault is to keep open for 1 hour. At the end of the hour, I used to get a notification asking if I still wanted to keep the vault open. 

Now - no notification and vault locks. 

How do I get this notification back?

As said on Windows 11 with April update - have not done May yet.

One of the most aggravating things about Windows and updates - is that some settings - not know to you or identified - are changed. And now you encounter different or unknown behavior. Incredibly frustrating when you just want your PC to work like you are used to.

Any ideas or help would be greatly appreciated.

Thank you!
