Samsung watch 5 BBT and glow app

Ally

Hey guys,

I bought the premium lifetime subscription to glow because it's partnered with samsung for menstrual tracking. From what I read it looks to use the watches BBT at night to sync with the app but I used it last night and nothing's coming up in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>.

Has anyone done this successfully or do you still have to manually enter BBT?
