I have to uninstall and reinstall the sp02 app every couple of days and also restart my phone every day for it to work. After a couple of days it stops working and I have to do the process again. Why won't it work continuously

Hi there, @58ts. Welcome to the Fitbit Community Forums. Thanks for bringing this to my attention and for the troubleshooting steps you've tried. I'm sorry to hear that the SpO2 on your Versa 4 is not working. I understand your concern, I will do my best to help you with this!
Please keep the following in mind to make sure your Fitbit device successfully measures your SpO2:
Turning off any clock face permissions can cause the clock face to stop functioning. To check these settings:
Your Fitbit device must be able to consistently track your SpO2 data:
Make sure your device is in contact with your skin.
Your device should be snug but not constricting.
Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.
For more information about SpO2, see: How do I track blood oxygen saturation (SpO2) with my Fitbit device?
