The application began to slow down after the update on January 28, 2022 (iOS)

The application began to slow down after the update on January 28, 2022. Online maps and local maps (rmap) slow down the same way. Is it possible to return to the previous version? I have been using the application for more than two years, I constantly use it when traveling, but now it is impossible! What did you do with it??? Please return everything as it was! I use 5.0.7 version.
I've send to you service report from app (today).
