Office 365MFA forcing every session not once per day

Question

we have recently set up MFA for our business using yubikeys, one of the things we set was that it would ask you to login using MFA once/day/device this works for most people, however, there are about three of us that are having to sign in once/session so if i log into office on chrome and then close the chrome window it will ask me to log-in again.

We have tried to fix the problem by;

Changing browser,
Making sure that cookies aren't deleted on close,
tried logging in on different device,
tried running chrome with the legacy SameSite cookies enabled,
tried completely removeing my user profile from the computer and relogging on,

None of these attempts have prevailed, can anyone help?

@Jake Seaborn Thanks for reaching out.

That should not be the case normally unless you might be getting targeted with another conditional access policy.
Make sure you are targeted with just the same set of CA policy like others.

You can also review the tenant wide configuration and confirm the settings as per : https://learn.microsoft.com/en-us/azure/active-directory/authentication/concepts-azure-multi-factor-authentication-prompts-session-lifetime#review-your-tenant-configuration

If you still have the issue, we will need to review your sign ins for which you will need to contact us at azcommunity@microsoft.com with subject "Atten-Vipul".
After further checks, we can create a support ticket for you, if required.
