Syncs zero data in Watch

I will request money back. When I installed the SPO2 app on iPhone, it initially synced from Health app correctly to Watch. But after I requested a manual reading of oxygen using the Apple’s Blood Oxygen app on Watch, SPO2 later showed zero data. It showed the correct time for last update, but showed “0%” data. The Health app showed correct updated data and so did the iPhone version of SPO2, but Watch data was zero. So I tried pressing “Sync Now” but that did not help. I tried rebooting both Watch and iPhone. This did not work. I tried removing the SPO2 app and reloading. This did not work. Only the iPhone SPO2 app works, but not the Watch version. Sorry, but you need more work to do on this. Let me know if and when you fix.
