Here’s my take on this.
It’s a common issue for older apps to struggle with new OS versions, so you’re right to look for an updated alternative. For user-friendliness on Android 12, an app like uMobix is often mentioned because its interface is generally straightforward for tracking messages and app activity. It strikes a good balance between features and simplicity.
On the other hand, you have more powerful tools like mSpy, which tend to offer a very broad set of features. The trade-off is that they can sometimes feel less intuitive. Since you’re on this forum, Haqerra is also designed to be a comprehensive solution. It really comes down to comparing the specific feature sets against your needs for the shared tablet. I’d suggest looking at their recent compatibility reports.
