Hello SpicyMama,
We understand that your daughter is able to use certain apps longer than the total amount of time you have set up in Screen Time settings. We know it's important for these settings to work like you expect them to, and we'd like to help.
First let’s check to make sure everything is set up correctly for this feature to work the way you want it to. When you set up Screen Time for that device did you do so using either Family Sharing or directly through the device itself by selecting "This is My Child's iPhone"? If not, make sure you do that using the steps here: Use Screen Time on your iPhone, iPad, or iPod touch.
We recommend choosing the option to set a Screen Time passcode as well, and make sure it's one your daughter would not know. If this issue is occurring during scheduled Downtime, go to Downtime in Screen Time settings and enable "Block at Downtime". Also, go to App Limits > [Limit Name], and enable "Block at End of Limit".
Lastly make sure the affected app has not been included in the "Always Allowed" section of the Screen Time Settings. Please respond back if she continues to be able to bypass the app limits you set.
Thanks for using Apple Support Communities.
Take care.
