App not working anymore

[grazipeach]

I tried to use the app and the tampermonkey extension, but it looks both aren't working. The app says no results every time I try to look for a sheet. I don't know if it doesn't work on officials, but even looking for other songs, nothing appears.
Thank you in advance!

Need more details on the extension not working. As for the app saying no results, try searching by title and author instead of by URL

This is happening for me as well, both searching by URL and typing in the title manually. Right before this started happening search results would appear, but anything I downloaded resulted in a 'server error' and didn't work
