DJ Mix Pads 2 - AI Music Mixer

I just bought the subscription for one year and it was really good. I made a few songs and then this morning the app crashed seven times. And crashed three times yesterday you have the restart your whole iPad or iPhone for it to open again. You would think getting the subscription would make the app run better. I hope this can be fixed because I love this app I would’ve put five stars but, its only three because it crashed every time I tried to record a song or even listen to them.

I think the app is amazing and I love using it just wish you had more material to work with like more songs and genre’s like riddim or traditional Chinese music mixed it. Some of your tracks try this and it’s brilliant. But after a few months I know all the mix’s I can create. I don’t want to loop them like a old recorded player same stuff so plz more mixes or songs in each genre/categories or simply more genres/ categories

How do i stop a purchase from a free trail my app isn't allowing me to open it either on my iPad , I have 6 days left for the free trail it's saids I must go to settings if I want to cancel but it's not allowing me that option I hope I don't have to cancel my debit card . If I delete this app will it automatically remove the purchase ???
