FINISH button not pushing form to the next level

Good day all

Nothing happens when user click FINISH to complete capturing. It just flicks to show its tapped.

I have never encountered this since I started using CommCare in 2015

Please help as i need to roll out on Friday

I haven't heard of that before - is it possible there's a validation error higher up on the form? Have there been recent app changes? Do you see this every time you fill out the form? Do other forms work like normal?

I have just run CommCare update from the Google play store and sorted the issue. Seems to be a new version on Play store. Thanks
