Update Onesignal SDK for Pro Users

I am a Kodular Premium user, My husband and my friend both have Kodular Premium accounts. All are yearly premiums. We are happy with almost all features except onesignal.
After paying so much why do we have to use third-party extensions for basic things? Why kodular do not take responsibility to improve this very essential feature? Why ?
Seriously guys is nobody facing any issues?? Why our dear kodular team is sleeping? Why do we have to purchase these plugins from third parties? then why premium?
