Puffin always worked perfectly for me. It was my go-to app for when I needed Flash. I was never disappointed with its workings. Some people started having problems with the app, which I am 100% sure the people at Puffin were prepared to fix, but it was simply out of their hands. Apple did not allow the Puffin team to make updates to the app through the Appstore because they saw them as a competitor. How unfair and unprofessional of Apple to handle it this way. Maybe instead of sabotaging your competitors, try making better content yourselves.
