ExchangeOnline module powershell and hybrid azure ad join

[AdamS777]

I have a conditionnal access control requiring hybrid azure ad joined device or mfa to access Exchange Online. Device is hybrid azure joined and has Azureadprt : Yes. When I try to connect to exchnage online (3.1.0 version) via powershell i got error that MFA is required. It looks like that  powershell cannot recognize the device as domain joined .
