Screen time parental controls Snapchat still open during downtime

I have set downtime on my daughter's phone yet Tik Tok and Snapchat are still available to be used during this time. I am very tech savvy so I have tried everything, from adding App limits for snapchat (even to 1min) yet I can still use it beyond 1 minute, made sure block at downtime is enabled and many other things I've read online (from switching the phone off to disabling and enabling share across devices etc).

I am appalled that Apple still hasn't fixed this issue considering we are dealing with the safety of our children. I have trusted Apple's apps always work but I have seen posts since 2018 talking about this issue and nothing has been resolved.

Does anyone have a solution?
