And isn't the script intended to be a workaround to App Store's restriction on allowing zaps? That implies that it's intended to work specifically to the app store version. I would try deleting the app, reinstalling from the App Store, running the script again, and seeing if it works. If not, delete the app you have installed and grab the test flight version and see if that works.  

 Yes. Should work for both. But would definitely start fresh. Takes two minutes. 

 For shits and giggles. Deleted Damus app. Did hard restart of iPhone. Download Damus from Apple App Store. Re authenticated. Run the script- result =0. Restarted Damus. Still no fraking zap icon. 

You lads are awesome but I am so done for tonight. 

 Damn. Tongue has to be on the right side of your mouth.. forgot to say.
