Sudden dip in Retention

Hey Team, we're seeing a sudden dip in our retention on the app store connect dashboard.

For the last 8 mo's it always remain ~90% retention (paid users --> paid to continue) but now we're seeing it to be ~16%.

Is anyone else also facing the same thing or do you know what can be the potential reason for the same?

PS: we launched a new tier in the same subs group on ~3rd Dec but seeing an impact from the last few days only.
