Apps bypassing downtime restrictions I.e. TikTok, teams, instagram, Snapchat

I have downtime restrictions enabled on my kids phones. However after we updated our phones to iOS 15.3.1 Snapchat, teams, instagram, YouTube, google Duo, and TikTok are bypassing the down time restrictions. I do have a screen time passcode setup and it has not been guessed. I have the phone in my hands and can see when I setup screen time that it’s not blocking these apps. I’ve tried logging out of his Apple ID then back in, I’ve tried removing and resetting screen time permissions. Nothing is working. This seems to be a wider issue not just with my phones but we need this fixed
