Hello Todd0213,
I totally agree with you. App Limits is a great feature. But only if it works. And for me it doesn't work for a while now. It is absolutely annoying when such a feature doesn't work reliably. And it has nothing to do with the version of iOS. Our devices ran all the latest iOS and some days there are limits and some days there are not. Then I'll set new limits and this works for one, two or three days and then they are gone again. And then comes the day where all limits are back. Then I've five limits for one app.
As Richard_uk10 said, Google does a really good job with Family Link. That works. Period.
We pay a ton of money for Apple products and such a important feature is only a mess right now.
Please take this serious and fix that problem.
And yes. I've tried all the tipps out there. Deactive, restart, updates. I've even reset my iPhone from scratch. Nothing works longer than a few days.
For the record. I set limits for my two Kids. They have different devices and that issue affects all.
