All of a sudden Samsung health app won't open on my phone s9, can't track the steps, heart beat monitor etc, has worked fine until today.

Hi @brewerboy. Please perform a Soft Reset. This doesn't delete anything from your phone, it fixes any minor issues that may be occurring. To do this, hold the 'Power' button and the 'Volume Down' button, both together for ten seconds and your phone will restart. Let me know if this resolves it!
