Using Glow with IUD

Ellen
Hi folks, so I got my IUD back in July and changed contraception in Glow settings but that meant it stopped telling me about fertile days and % chance etc. I'm guessing this is because the hormonal IUD mucks with your ovulation but with the nonhormonal IUD, periods etc aren't effected..
Anyone else noticed this? or know a way of getting it back? Or can I request that The Powers That Be at Glow HQ make 2 options in settings to distinguish between the types? Or am I wrong about the way the non hormonal IUD works? Thanks!
