Problems with mobile app

I've recently been having several issues with the mobile app (Android) and was wondering if anyone knows of a solution.

First, the search function no longer works. No matter what I search, with whichever filters, nothing happens and the main page with the highest viewed scores of all time are displayed. I've tried reinstalling the app and clearing data, however they only fix the issue briefly.

Second, the app is draining my battery in the background at a pretty extreme degree. I have a Samsung Galaxy S8+, and the app uses ~5% battery per 30 mins in the background, forcing me to force quit every time I exit it.

If anyone has any idea on fixes that would be great, I'm currently pretty much unable to use this app.
