NEW Conditional access policy for internal network: Need advice

[Koops]

Hi,
I've set up a test conditional access policy in one of my tenants to exempt users on the local network from (MFA).
However, the devices are still prompting for MFA. I'm hoping someone can review my settings and advise if they are correct.
My Configuration:

• Named Location: Created a named location with my internal IP range.
• Policy:
  • Users: One test user account (for testing purposes)
  • Target Resource: All cloud apps
  • Conditions:
    • Device: Any device
    • Location: Any location except my named location (internal network)
  • Client apps: Not configured
  • Filtered for devices: Not configured
  • Access Control: Grant access, require MFA (except when conditions are met)

Question:
With this configuration, should the devices stop asking for MFA after the initial login when on the internal network?
Or will they continue to prompt for MFA every time?

Thanks for any help given
