iOS 11.3.1 - Creating a EASession with my connected mfi accessory return nil

Creating a EASession with my connected mfi accessory return nil often.

The error states that the session couldnt be close (but no session from code was never opened directly)


The only way we can get a session when this happen is to disconnect the accessory in bluetooth settings and reconnect it.

this problem started with ios 11.3


is this a known bug ?

anybody else encountering this issue ?


thanks

Mat
