Spatial 3D Studio no PLY export

Spatial 3D Studio all of a sudden the developer took out PLY exports and replaced it with a compressed spz file. I paid 80$ for the app and I want to know what's happening.

To the developer are you bringing back PLY export support? People can't open spz files. PLY is the file thats widely compatible. I'm thinking of getting a refund. This app is very expensive as it is and missing PLY export support is not good. I hope I get an answer.
