To developer - will you be fixing this app since it currently doesn’t work for paying users. I’ll change my review once a fix is posted. Simple hello program ran but everything else fails with mysterious error message.
The example program can be compiled and executed one time, producing the expected output. If you hit "Run" again, you will be prompted to buy compilations. That's fine with me, the first "compile and run" was successful, so I paid for unlimited compilations. This is where it becomes a disappointment: no matter what I type in my program, the output is always: "Wrong __data_start/_end pair". If I run the "Hello World!", without changing anything, it works as expected. If I modify it, even by adding a single character to the string being displayed, the result is "Wrong __data_start/_end pair". If I run an empty program, there is no output but that's expected. If I add an opening parentheses and a closing parentheses, the result is "Wrong __data_start/_end pair".
I get the subscription model. The app doesn’t seem to be advertised as free to me so that’s fair. But I’m. It going to pay without at least getting a few free compilations to test it. That’s absurd.
