Rating Upgradation

I’m sonu_11, started to participate in codechef challenges in recent months, facing issue in rating. I have participated in January long challenge-II and February long challenge-I, JAN222B and FEB221B respectively and scored pretty well. But rating is not upgraded in my account. Just wanted to know if its common on codef to get rating this delay ?
Am i loosing my ratings for some unknown reasons ?

same problem with me bro how to sove

I am new to division 2 as like you, and so don’t know that long challenges can be unrated for division 2, and those two were unrated.
