Smart Stack auto rotation

Good afternoon John_hgn,

Welcome to the Apple Support Communities!

It sounds like you are trying to use a Smart Stack on the Home screen. Which apps do you have in a Smart Stack, and what are you expecting to happen in the rotation? Try creating your own widget stack instead of a Smart Stack and see if you get different results using the same apps. Also, test with different apps.

Use widgets on your iPhone and iPod touch

"Create your own widget stacks

1. Touch and hold an app or empty area on the Home Screen or Today View until the apps jiggle.
2. Drag a widget on top of another widget. You can stack up to 10 widgets.
3. Tap Done.

Edit a widget stack

1. Touch and hold the widget stack.
2. Tap Edit Stack. From here, you can reorder the widgets in the stack by dragging the grid icon . You can also turn on Smart Rotate if you want iOS to show you relevant widgets throughout the day. Or swipe left over a widget to delete it.
3. Tap  when you're done."

If the issue persists, please reply to this thread and we'll do our best to help you!

Take care.
