S7 edge Ive been using ac display on my OPO for over a year and have had no major issues. Currently running it on a s7 edge and have noticed a reoccurring issue. After my alarms trigger and go off  ac display does not function properly on the lockscreen. It no longer appears on my lockscreen. So far the only solution for me has been to either restart the device or toggle the on/off button in the ac display app settings. Please advise if anyone has insight  thanks!
