Recent changes:
Due to changes in Google's policies, it is becoming increasingly difficult to maintain the quality of the app. For this version, in order to meet Google's requirements, we had to make significant changes to the app's internal structure that could not be maintained any longer. Therefore, there may be issues that we did not anticipate. Please take this into consideration and update the app accordingly.
