We changed the way the "late" period function works in the app based on user feedback. Instead of pushing the prediction forward by a day or so, if a period is late (based on Glow’s initial prediction), the app will grey out the prediction and wait until you manually input your period if/when it arrives. When you do so, your future predictions will return as well, as these are based on your confirmed period.
How does Glow deal with late periods?
