Alarm volume turns low after the first ring
I have an I phone pro max 12. after the last update my alarm suddenly is not working properly. it will ring once, then go very low and i am sleeping through it. what happened and how do i fix it? i have already tried sounds and haptics and the volume is up. i have turned it off in an attempt to re-set it. neither of these things work.
