Simple earn apr

I’ve had a locked woo earn for 106 days now which ends or renews after 120 days. And up untill a number of day ago it was at almost 50% apr. Then it decreased as soon as to round 32%, and now i discover it’s been decreased once more to 19.8%

Similar factor occurred with ape. I locked in at 92%/120 days only to see it decreased to 69% 6 days later.

Why does this happen? I imply i might understand if they might change apr on renewal nevertheless it feels silly to lock your money into an earn with a certain apr, to see it closely lowered a number of days later.

I know it’s in all probability of their phrases, but with a penalty for taking the money again out, this simply seems like cheating.
