Other than the program preview, are you having other issues?
I think moving forward it’d be better to fix the bugs in 2.0 than reverting back. Furthermore, 2.0 offers some new features including logging support for the mobile app. I will take a look at the program preview and see what I can fix however just to clarify, is it just the preview thats wrong or are the programs running incorrectly in 2.0?
Thanks
