I have this issue, too. I have to reset all parental controls with every single update. Not all devices need to update to trigger the reset of everything - just my own phone updating triggers a reset across all my kids' devices. The thing is, I have updates on automatic. So when there is an update I don't always know. My kids get access to everything, including adult websites! It is so annoying. As I have parental controls set to only allow certain websites, I have to re-add all the websites they're allowed to browse. For my older child it was in the hundreds. It's so frustrating! Every single parental control gets re-set. This is a huge issue that Apple needs to fix NOW. I'm so tired of of it. I'm so tired of reading - reset your phone, or don't give your kids the password. It has nothing to do with that! It is triggered by Apple updates. Spending hours again this morning resetting everything for my kids, and I'm beyond frustrated with Apple for not fixing this yet.
