After the latest update on the S6 lite 2024 edition today and latest update for nomad, I can no longer export to OBJ at all stl is temperamental, I have tried the usual work around and this has happened before but even they aren’t working please help 
Could you give more information? It works fine for me when I try on Android.
What’s the polycount/size of the scene and does it crash or does it do nothing?
