Being able to open songs from the trial version to full ver.

I've been working on the trial version of the app for around 2-3 years and all I did was play around with it.
I eventually started to make music with what I had at my disposal and quickly gained knowledge on how the app worked. And recently, I bought the full version of the app with the intent to add to my past works with new instruments and settings. I was hesitant about buying it because I didn't know if it would keep the songs I've worked on for so long, that I saved up since 2 years ago. I was planning on saving them and uploading them for the world to hear. But unbeknownst to me, there was never an option. I felt like I wasted my 15 dollars and regretted my decision to pay real money towards an app I use on occasion. So, if anyone from the team reads this, I'd like to request an option to either move data from the trial version, that is already in my device to the full version, or find any other way to appease my decision.. I was looking forward to seeing the music I made with the app online.
Thank you, and have a nice day.
