After reading the original blog post I went to remove my account from the app. It asked to provide always on access to location and when I refused I couldn't even reach app's menu. I removed the app and used the same link you provided to remove my account, and mentioned my experience in the comment section. Now they sent me an email saying that my account is still active and they'll fix the app. The fact that process of closing my account is not a single button press and is taking me more than two days is beyond ridiculous and infuriating to be honest.
I have to state my reasons as a required field, AND wait for their "approval" to delete my own account? WTF is this shit.
I get a 404 past the telephone/email entry page...
