Recurring Alarm with no activity in logs

My AC300+B300 unit emits an audible alarm every morning between 8am and 9am (roughly) with 5 recurring tones, but there is no alarm logged on the digital panel (nor in the phone app, which is practically useless) so I am not sure what is happening. Is this recurring alarm a common experience, does anyone know what this might be, and is there any way to confirm exactly what the alarm is telling me? I’m frustrated at the lack of information the unit provides.
