Old Alarm rings as notification despite being turned off
After moving from a really old iPhone, I transferred all the data within it and made sure it's a 1:1 copy. But apparently, the transfer is a bit buggy due to the distance between the software version. One of the bugs is the alarms from the previous phone actually ring but only as a notification, even after I turned them all off in the clock app.
Is there anything I can do aside from factory reset? That will be appreciated.
