Gemini used to listen to my tracks and give great feedback but not anymore

For some days, I used Gemini as an assistant for my music production. I felt very hopeful. It listen to the live set I produce and it gave me incredible feedback: were i should give more time, stuff that i have to do o sound more pro etc. It was very creative and interesting hours. Since today, Gemini went dumb and while I use the same chat where I downloaded my set, it disregard it and pretend now that it can't listen to it.

thanks for your help
