I had this issue but found this fix in web search. Check under "Battery" if Low Power Mode is turned on. If it is, turn it off and Always On Display will work again!

I did do a forced restart after turning off low power mode because that mode set Auto Lock at 30 secs and grayed it out so I couldn't change it. Maybe the forced restart got rid of the bug but I am just glad Always On is working. Hope your issue gets fixed soon.
