its funny but i actually had this issue in 6.10,13and 6.10.20 has fixed it for me. my whatsaapp led is finally green now.
I did a factory reset after flashing 6.10.20 through twrp, maybe its that?
what i got now is the swipe up search page like dimmed or greyed out, still usable though.
im on 3s prime international and im pretty happy with the rom, fast and stable and the battery is ok, but i think that could be better. im on 2 1/2 days with 35% left since upgrade, but it has been light usage ( under 6h sot) with greenify.
