Thank you guys, I managed to get into the app again and immediately deleted it. Won't be using this product ever again.

Hello,
as your locking app is FAR from perfect, I'm now locked out of my phone, without the ability to get back in. Before pointing out the obvious: yes, I properly set up my ring, lock screen etc. Unfortunately it was activated before I could set the pin, as I rebooted to see if it really took over the lock screen. My gmail credentials are "invalid", according to your app, and I’m sure I use the right gmail account and password, and no, 2 way authentication isn’t activated. Anyone any ideas?
Thanks in advance, David
