Hey Jesse! It's frustrating when the browser doesn't cooperate, but let's get this sorted. It seems like a glitch where the flavor selection isn't sticking on the 5% nutrition website for you. Since it's working fine on other browsers, let's try some troubleshooting steps. Firstly, ensure your Firefox for iOS is up to date. Then, clear your browsing data (Settings > Clear Private Data). Restart the browser and give it another shot. If the issue persists, you might want to try disabling any add-ons you have. If none of these work, reaching out to the website's support might be a good step. Hope this helps you enjoy a smooth purchase experience soon! Let me know how it goes.
