Coming off the pill - How long until glows predictions started working?

Been off the pill since July, taking a while to settle into a pattern again. Glow is telling me I have a 64 day cycle next period due in January. I am recording bbt but it doesn't seem to change predictions.
Yet my other app seems to be updating with bbt data inputs.
Is there some way I can input ceasing the pill or will it just take time?
