Trouble with Apple Watch working with app?

Ja

I used to be able to use my Apple Watch to add diapers and slee timers but now it always says “Please log into the glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby app</a> in your iPhone” even though I already am signed in on my iPhone. Just doesn’t work anymore on my watch.
