Issues on SE 2 *update below*

I purchased the full version of Let’s Unmix. I have an iPhone SE 2. I am impressed with the algorithm to remove vocals and separate tracks. However for some reason most of the songs I am trying to use, once they are loaded and have been “unmixed” they have blank spots throughout playback of the song. To put it simply, on average of every 30 seconds there are 5 to 10 sec places of silence. I’ve uninstalled the app, reloaded it. I don’t know what else to try. In the demo, I thought it was being caused by a glitch in the advertisements that pop up. But even after buying, it is still doing it. It makes it unusable. Unless you can tell me how to fix this, I would like a refund. 1 star for now, but if this is fixed it is easily a 5 star app. All my music plays with no issue in other apps.
*update*
I contact the dev and they immediately responded and asked for more details of the problem. After several responses back and forth, they figured out the issue and did an update. It is working perfectly now!!!! This app is exactly what I was hoping for and does what it advertises. I am especially impressed with the dev response to the issue and would purchase from them again.

Was not expecting that. Thoroughly impressed

Like another comment said, I don’t often write reviews for apps, and when I do, it’s mostly only for if I think an app is garbage. But this app actually motivated me to come write a good review. I honestly didn’t really expect this to work tbh, but I said screw it, it’s free to try... and my mind was blown! This dev deserved every bit of my 5 bucks for the full features (export, full song length, etc). Honestly after hearing how well it worked, I would have easily paid more. I’ve been wanting something that does this since I was a little kid but didn’t think it was really ever possible. So here I am, smiling like a little girl on her birthday, plugging in all my favorite songs. And it just works, all you do is load in the song and tap a few buttons. In a world of subpar subscription service apps, this is quality app development, many thanks to the devs!

I’m speechless

Seriously. I rarely write app reviews, but I’ve been working on a remix and I was struggling with the vocal samples, as I didn’t have the a cappella version of the song. I tried Audacity, EQ, etc. Never got to a place I liked. Then someone put this app on reddit and I decided to check out, but I wasn’t confidently it would be better than what I had done before. Being free also lowered the barrier to try it out. And boy it was worth it! I still can’t believe what this app has done with the song. It really feels like magic and the vocals are perfectly isolated. I bought it in a heartbeat. It solved my issue in 3 seconds. Congrats developers!
