I've beta tested apps in the past and at first it was interesting, especially to get the app and use it, but in the name of due diligence and give the developer the feedback, required work. I also had to put up with a lot of bugs, issues and instabilities.
One thing I would never do, is run the iOS beta on my phone. Now that apple allows public betas, I don't go near that, just because my phone is needed for work
Gd to know and get feedback! Thanks.
