Quick question. I was just using Proxyman on iOS and was thinking of upgrading to pro. I tried to redeem the code found on https://proxyman.io but it did not work I double checked that I had no spelling errors. Just so that you can check if everything is working as intended...

@georgbachmann The iOS app uses different discount codes. You can find the code in the Paywall screen -> Click on the Redeem Discount code -> It will show the code -> Copy and redeem it in the same view 👍
