I would like to help with this project, I have quite a bit of experience in app development mainly in Android Native and React Native.
Regarding the application, the most important thing will be to see that the libraries have been updated and are compatible with the new version.
Also in the new version, there have been changes regarding the request for permissions and the saving of files, it will be necessary to see if it will be necessary to update the way in which permissions are requested.
I will check your project in order to find what's going on
My main objective is to help you in the best possible way, exceeding your requirements. The most important thing for me is to obtain your 5 stars and that you are satisfied with the service.
