Users auto logout issues Sage CRM 2019 R2

SUGGESTED

We are having some issues with users getting logged out of Sage CRM after 30 minutes of inactivity.

Here are our settings...

1.  CRM App Pool.  Process Model ---> Idle Time-out = 0

2.  CRM -> Administration -> Users -> User Configuration -> User Inactivity Timeout = 720

Note.  Attempted to set the User Inactivity Timeout to 0.  However, it automatically updated itself back to 30.

We set the timeout to 720 about a week ago.  However, today, it was set back to 30.  Is there something that "auto resets" this?

Also, Auto-logout is set to Yes.  I wanted to update that to No.  However, this field is grayed out.  I don't remember this being grayed out in the past.

Two questions here.

1.  Can you no longer set the User Inactivity Timeout to 0?

2.  What causes the system to auto reset to 30 minutes?

Any assistance would be greatly appreciated.  Thank you!
