If you still have Refocus installed, let’s first try to fix the problem by using Refocus.
You now have Refocus deleted, you restarted the device multiple times, but the apps are still blocked. It could be that something else that’s not Refocus that is blocking the apps.
In iOS, go to “Settings” app, press “Screen Time,” press “Downtime” and ensure there is no Downtime scheduled.
If (1) does not resolve the issue, in iOS, go to “Settings” app, press “Screen Time,” press “App Limits” and ensure there is no app limit set.
If (2) does not resolve the issue, go to “Settings” app, press “Screen Time,” and see if you have a “APPS WITH SCREEN TIME ACCESS” section. If you do, ensure all apps there are turned off.
If (3) does not resolve the issue, go to “Settings” app, press “Screen Time,” and turn off Screen Time by pressing “Turn Off Screen Time.”
If (4) does not resolve the issue, restart the device again.
If (5) does not resolve the issue, try to force restart the device.
