Glow Prediction Issues

So recently I read a post from Glow that they had updated their algorithms for period/fertile window predictions to make them more accurate, but so far, for me, it seems less accurate. My cycles usually last an average of 42 days, but with the recent algorithm updates, Glow is acting as if I have normal 28 day cycles, (despite all the info I've been inputting for the last 8 months) and predicting my fertile window and my next period start date accordingly, which is really annoying. My last period ended April 1st, but already Glow is predicting that I'll start again at the end of the month, which is highly unlikely. Since my cycles are normally longer than 28 days, I also doubt that Glow's predicted dates for my fertile window are accurate... how can I fix this?
