Hi there, I am probably responsible for half of the views in you extensions directory 
I have knowledge about this extension since long time ago - there is even a comment of mine at thunkable official topic about the extension. But I have tried to contact the developer many times and he never answered.
Just to confirm, I searched for it again now and there is another user saying that it doesnt’t work and apparently the developer doesn’t intend to update it anymore.
Also, I am since last year trying to find someone to make a similar extension - see here: Budget for extension , but I could never find someone
