Well it worked but the error was {"error": "Unknown"}
BUT I figured it out! Your app wasn't able to handle special chars in my password. I changed my password to something without special chars and now it works!
Specifically I had the special chars { [ @ } < . and # in my password. So somewhere here is the issue and some kind of character here is breaking your password field or your API request. Maybe some escape you're doing?
Sounds good! Thank you for your help! :) Btw, the app works great now that I can test it. One suggestion: Big posts shouldn't be fully visible in the feed. It'd be better if you'd see a preview and had to click on it to see the rest of the post. But besides that it looks awesome!
