I LOVE Loopy, but....

Ive used this wonderful program for years, as far back as my Ipad 1, and I love it. I wrote so many things on it, I have used it in concert, and Ive developed ways to use it that the people who wrote this app didnt even imagine. On the Ipad pro, its wonderful.
That is why I was disappointed the other day when the app started malfunctioning, and just when I needed it. The sound was weird, and other glitches made it totally un-usable. I had to dump it and re-load it, and I lost almost a year of compositions. Now I have to re-compose a bunch of stuff that I use in concert, and thats VERY frustrating. Any suggestions? I really like the app, but losing all of that made me wonder if its really something i can use professionally.
