Question Problems with Galaxy Flip 5 and Google Assistant when phone is closed.

[HTM520]

Hi everyone. Recently Google Assistant has stopped responding to me when my Galaxy Flip 5 is closed. If I unfold the phone it works as expected. 'Hey Google' activates the Assistant when the phone is closed but will not respond anymore beyond that unless the phone is open. I haven't made any changes in settings and no update has been installed since I started having the issue. Is anyone else experiencing this? Any ideas to solve it?
