Check if there's any automatic logout configured for M-Files Mobile: Specifying the Automatic Logout Time in M-Files

Other than that my limited understanding is that the authentication requirements would be primarily controlled by Entra ID and are not something M-Files Mobile can really affect in these federated authentication scenarios. I suggest checking Microsoft support resources for the Entra ID configuration guidance. It could be related to the Conditional Access policies, for instance.
