Prisma3D Legacy

I've used this for a little while and it seemed decent for a mobile 3d editor. But recently I was working on a pretty intensive scene, and after many crashes and problems, when I was like FINALLY about done it crashed and erased everything in the project. Like everything. This took me so long to make and I can't believe I lost it all.

Hi Prisma 3D ( Legacy ) developers, I enjoy using and learning a bit of 3D modeling and 3D animation on it so far, but I want and need some things like important features on this program or app and its sibling app also like clay sculpting model features ( best app as reference is Nomad Sculpt there ) and texture painting for easy modeling and texture map making, ability to import and export different 3D model format files like .obj, .stl, .gltf, .glb, .fbx, .dae, .3mf, tons and so on please.

each time i get out the app for few second then i try to resume back my project was gone before i manage to save i dint even completly close the app yet i need to start from scratch very bad im so angry and frustrated i cant do project one time i cant save my project like what i spend 30 minute doing it now it gone like that
