Maybe it would be better to create them dynamically
Edit:
Try this, it’s similar to what Still-learning suggested but not identical.
I also recommend using CheckBox.Click because the Changed event is triggered even when the screen is initialized, causing the data to be saved again unnecessarily.
Keep in mind that the number of elements in the list must be the same, otherwise it causes issues with index selection.
However, I strongly recommend generating these elements dynamically, either with DynamicComponents or RecyclerList.
