I just updated to 2.3 and when I try to access some of the features in the text window, nothing happens. So, if I type something and try to change to see the initial forms, nothing happens in the text window. I was able to do it one time after I installed the update, but never again even after restarting the software and my Mac several times.
This used to happen in the previous version, but I was able to just restart the software and I would be able to change features at least once.
PS - I can change and see the ss01, ss02, but not the Initial forms
Initial forms are not supported from the features. They only works for Arabic if you set the view to RTL and are calculated independently from the feature code.
