My FileManager - Documents

I use this app to play my downloaded music, I love that it has a sleep timer, and shuffle play and that it’ll auto play the next song. The problem is ever since I updated it, songs that used to work perfectly fine either get fully auto skipped (sometimes to random spots in the song, sometimes completely) if you try to go back it won’t work, and it’ll skip multiple songs in a row sometimes, sometimes trying to fix it makes even more of the songs skip and it’s really disappointing. Also I think it’s annoying that ads were added to it. Please fix this app I literally use it every day, if you fix it I’ll make my review 5 stars, because I love this app, I just want it to work right again

After the update to the last version, I can't download any videos that can fix this problem

I like the app so much, BUT there are two issues: -The first was since I downloaded the app which is the video, if I am watching the video and I pause it to check another app or someone calls me...etc, when I come back to the video I found only the audio, I had to get out of the video and go back to the playlist and click on the video and start over. -The second just happened after the update before this last one, when I raise the volume from my headphones I see the big dot/ball going opposite towards the sign of volume down, and same thing happened when I lower the volume I see it going towards the sign of volume up, also the same issue if I touch it to raise or lower I have to move the opposite side of what I want. Thank you
