I am following this thread and read what you've said above. If you're able to download it from the external link, who gave that to you kindly share the link because there are scammers and hackers that want their victims to download the app that they've made, a copycat to say. If you have downloaded that app that shows with 500k+ users, I guess you're fine but then I'd agree to the suggestion that if you're able to access there, use a better one and move your funds.
